Pearson’s r Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 Lesson Quantitative Research 1 Designs What’s In Quantitative research is more systematic and controlled than qualitative. However, both research methods have a statement of the problem to investigate. At this point, it is assumed that you are already done stating your research problem, the background of the study, scope and delimitation, hypothesis, conceptual framework, and review of related literature and studies. Each type of research has a unique design to follow that will also lead the direction of sampling procedure, data gathering, and data analysis. Each research type also aims to answer specific research questions; how it will be answered is determined by its design. Important considerations also are the variables of the study. The type of variables provides paradigm (your conceptual framework), which helps the researcher decide on what will be the design of the study. So it is very important that you have completed the previous tasks diligently to maximize your learning in this Module. In this lesson, you will be taught how to select an appropriate quantitative research design. What I Need to Know Meaning of Quantitative Research Designs When a man decides to build a house, does not he draws first the blue print before he will start to do the work? Same with the conduct of research, the blueprint for the collection, measurement, and data analysis is drawn as a pattern to follow. Furthermore, research designs enable the researcher to obtain a more valid, objective, reliable, and accurate answers to the research questions. Research design is defined as the logical and coherent overall strategy that the researcher uses to integrate all the components of the research study (Barrot, 2017, p 102). In order to find meaning in the overall process of doing your research study, a step-by-step process will be helpful to you. In quantitative research, you are going to have a great deal of abstraction and numerical analysis. According to Fraenkel and Wallen (2007, p 15), the research designs in quantitative research are mostly pre-established. Hence having an appropriate research design in quantitative research, the researcher will have a clearer comprehension of what he is trying to analyze and interpret. 1 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 What’s New Activity 1: Plan Your Work Directions: Pretend that you are conducting a study on academic adjustments of teachers and students on the learning delivery modes during this time of COVID – 19 pandemic. Come up with a plan on how you are going to obtain the necessary data for this study. Draw a procedural flowchart to illustrate your plan. Study on Academic Adjustments of Teachers and Students on the Learning Delivery Modes during COVID – 19 Pandemic “Plan of Work Flowchart” 2 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 What Is It Types of Quantitative Research Design Quantitative Research Designs have five general classifications: descriptive, correlational, ex post facto, quasi-experimental, and experimental. Descriptive Research. When little is known about the research problem, then it is appropriate to use descriptive research design. It is a design that is exploratory in nature. The purpose of descriptive research is basically to answer questions such as who, what, where, when, and how much. So this design is best used when the main objective of the study is just to observe and report a certain phenomenon as it is happening. Correlational Research. The main goal of this design is to determine if variable increases or decreases as another variable increases or decreases. This design seeks to establish an association between variables. It does not seek cause and effect relationship like descriptive research; it measures variables as it occurs. It has two major purposes: (a) to clarify the relationship between variables and (b) predict the magnitude of the association. However, the extent of the purpose of correlational research depends on the scope and delimitation of the study. Ex Post Facto. If the objective of the study is to measure a cause from a pre-existing effects, then Ex Post Facto research design is more appropriate to use. In this design, the researcher has no control over the variables in the research study. Thus, one cannot conclude that the changes measured happen during the actual conduct of the study. The last two types of quantitative research designs are identifiable for the existence of treatment or intervention applied to the current research study. Intervention or treatment pertains to controlling or manipulating the independent variable in an experiment. It is assumed that the changes in dependent variables were caused by the independent variable. There are also two groups of subjects, participants, or respondents in quasi- experimental and experimental research. The treatment group refers to the group subjected to treatment or intervention. The group not subject to treatment or intervention is called the control group. Quasi-Experimental. The term means partly, partially, or almost – pronounced as kwahz-eye. This research design aims to measure the causal relationship between variables. The effect measured is considered to have occurred during the conduct of the current study. The partiality of quasi-experimental design comes from assigning subjects, participants, or respondents into their groups. The groups are known to be already established before the study, such as age educational background and nationality. Since the assignment of subjects, participants, or respondents are not randomly assigned into an experimental or control groups, the conclusion of results is limited. Experimental Research. This research design is based on the scientific method called experiment with a procedure of gathering data under a controlled or manipulated environment. It is also known as true experimental design since it applies treatment and manipulation more extensively compared to quasi-experimental design. Random assignment of subjects or participants into treatment and control group is done increasing the validity of the study. Experimental research, therefore, attempts to affect a certain variable by directly manipulating the independent variable. 3 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 What’s More Activity 2.

Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 7 Lesson Sampling Procedure 2 and the Sample What’s In Remember when you were taught how to write your scope and delimitation, you stated the subjects, participants, or respondents of your study. You also described their characteristics which qualify them to be the source of your research data. The next question you have to answer is, how many of the subjects, participants, or respondents should be selected as a source of data? This lesson will teach you how to describe sampling procedures in quantitative research. Note that the sampling procedure should be aligned to your chosen research design. Since you have already decided the research design of your study, then you are ready for this lesson. What I Need to Know Population and Sample The first step in determining the sample size is identifying the population of the topic of interest. The population is the totality of all the objects, elements, persons, and characteristics under consideration. It is understood that this population possesses common characteristics about which the research aims to explore. There are two types of population: target population and accessible population. The actual population is the target population, for example, all Senior High School Students enrolled in Science, Technology, Engineering, and Mathematics (STEM) in the Division of Cagayan de Oro City. While the accessible population is the portion of the population in which the researcher has reasonable access, for example all Senior High School enrolled, STEM strand at Marayon Science High School – X. When the whole population is too costly or time-consuming or impractical to consider, then, a sample representative is identified. Sampling pertains to the systematic process of selecting the group to be analyzed in the research study. The goal is to get information from a group that represents the target population. Once a good sample is obtained, the generalizability and applicability of findings increases. The representative subset of the population refers to the sample. All the 240 Senior High School Students enrolled in Science, Technology, Engineering, and Mathematics (STEM) Strand in a school, for example, constitute the population; 60 of those students constitute the sample. A good sample should have characteristics of the represented population – characteristics that are within the scope of the study with fair accuracy. Generally, the larger the sample, the more reliable the sample be, but still, it will depend on the scope and delimitation and research design of the study.

In order to check if it tastes good and ready for serving, what will you do? Answer: I will….. ______________________________________________ ______________________________________________ ______________________________________________ https://bit.ly/2BfQXHJ What Is It Approaches in Identifying the Sample Size Heuristics. This approach refers to the rule of the thumb for sample size. The early established approach by Gay (1976) stated by Cristobal and Dela Cruz-Cristobal (2017, p 172), sample sizes for different research designs are the following: Number of Research Design Subjects/Participants Descriptive Research 10% to 20% maybe required Comparative Research 15 subjects or groups Lunenberg and Irby (2008), as cited by Barrot (2017, p 107), also suggested different sample sizes for each quantitative research design. Number of Research Design Subjects/Participants Survey 800 Correlational 100 to 200 Ex post facto 30+ Experimental 30 or more Literature Review. Another approach is by reading similar or related literature and studies to your current research study. Since you are done writing your review of related literature and studies, you might want to recall how these studies determine sample size. Using this approach increases the validity of your sampling procedure. Formulas. Formulas are also being established for the computation of an acceptable sample size. The common formula is Slovin’s Formula. Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 9 Slovin’s Formula: N n= 1 + Ne2 where: n is the sample size N is the population size E is the desired margin of error 600 n= 1 + 600 (0.05)2 600 = 1 + 600 (0.0025) 600 = 1 + 1.5 = 240 Power Analysis. This approach is founded on the principle of power analysis. There are two principles you need to consider if you are going to use this approach: these are statistical power and effect size. The probability of rejecting the null hypothesis is called statistical power. It suggests that indeed there is a Useful online relationship between the independent and dependent tools: variables of the research study. The ideal statistical power of a research study is 80%. With the statistical power, it will be used to identify the sufficient sample size for measuring Visit the the effect size of a certain treatment. The level of difference following links to between the experimental group and the control group practice the power refers to effect size. analysis approach. If the statistical power tells that relationship between https://bit.ly/37Ia3lC independent and dependent variables, the effect size https://bit.ly/2AQpDQn suggests the extent of the relationship between these two variables. Henceforth, the higher the effect size, means the greater the level difference between the experimental and control groups. For example, your research study reveals that there is a difference in the pretest and posttest scores of the students in the given anxiety test after implementing a psychosocial intervention. With the effect size, you will have an idea of how small or large the difference is. Probability Sampling in Quantitative Research Simple Random Sampling. It is a way of choosing individuals in which all members of the accessible population are given an equal chance to be selected. There are various ways of obtaining samples through simple random sampling. These are fish bowl technique, roulette wheel, or use of the table of random numbers. This technique is also readily available online. Visit this link https://www.randomizer.org/ to practice. 10 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 Stratified Random Sampling. The same with simple random sampling, stratified random sampling also gives an equal chance to all members of the population to be chosen. However, the population is first divided into strata or groups before selecting the samples. The samples are chosen from these subgroups and not directly from the entire population. This procedure is best used when the variables of the study are also grouped into classes such as gender and grade level. You can simply follow the steps from this given example: A population of 600 Junior High School students includes 180 Grade 7, 160 Grade 8, 150 Grade 9, and 110 Grade 10. If the computed sample size is 240, the following proportionate sampling will be as follows. The number of members per subgroup is divided by the total accessible sample size. The percentage result of members per subgroup will be multiplied from the computed total sample size. After obtaining the sample size per strata, then simple random sampling will be done for the selection of samples from each group. Sample Size per Subgroups 180/600 =.30x 240 = 72 Grade 7 students 160/600 =.27x 240 = 65 Grade 8 students 150/600 =.25x 240 = 60 Grade 9 students 110/600 =.18x 240 = 43 Grade 10 students 100% 240 respondents Cluster Sampling. This procedure is usually applied in large-scale studies, geographical spread out of the population is a challenge, and gathering information will be very time-consuming. Similar to stratified random sampling, cluster sampling also involves grouping of the population according to subgroups or clusters. It is a method where multiple clusters of people from the chosen population will be created by the researcher in order to have homogenous characteristics. For example, a researcher would like to interview of all public senior high school students across Mindanao. As a researcher cluster will be selected to satisfy the plan size. In the given example, the first cluster can be by region, the second cluster can be by division, and the third cluster can be by district. Another way of doing cluster sampling is illustrated on the figure on the right side. https://bit.ly/2UTiZzp Systematic Sampling. This procedure is as simple as selecting samples every nth (example every 2nd, 5th) of the chosen population until arriving at a desired total number of sample size. Therefore the selection is based on a predetermined interval. Dividing the population size by the sample size, the interval will be obtained. For example, from a total population of 75, you have 25 samples; using systematic sampling, you will decide to select every 3rd person on the list of individuals. 11 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 What’s More Activity 1.

The same thing when getting information for answers to a research problem, tools, or instruments should be prepared carefully. In constructing a quantitative research instrument, it is very important to remember that the tools created should require responses or data that will be numerically analyzed. Research Instruments are basic tools researchers used to gather data for specific research problems. Common instruments are performance tests, questionnaires, interviews, and observation checklist. The first two instruments are usually used in quantitative research, while the last two instruments are often in qualitative research. However, interviews and observation checklists can still be used in quantitative research once the information gathered is translated into numerical data. What’s New Activity 1.

Let’s read Directions: Read and analyze the given scenario. Answer the guide questions below. A culmination program was scheduled for Grade 12 students. The highlight of the program is the presentation of the festival of dances. The six sections prepared for the said dance contest during the culmination. A month before the activity, the students already started planning. Their parents were also very supportive in the preparation of their costumes and props. The class advisers also monitored the practices in their classrooms. During the contest, the PE teacher invited teachers from other schools to serve as a judge. The performances were exemplary, especially the section Rydberg. The section was also a crowd favorite. However, another group that performed poorly compared to Rydberg was pronounced as the winner. Due to the result of the contest, Rydberg and other sections wanted to know the bases for judging. After conducting an investigation, it turned out that no clear criteria were set, and no rating sheets were used. Guide Questions: 1.

The type of instrument, reasons for choosing the type, and the description and conceptual definition of its parts are some of the factors that need to be decided before constructing a research instrument. Furthermore, it is also very important to understand the concepts of scales of research instruments and how to establish validity and reliability of instruments. Characteristics of a Good Research Instrument Concise. Have you tried answering a very long test, and because of its length, you just pick the answer without even reading it? A good research instrument is concise in length yet can elicit the needed data. Sequential. Questions or items must be arranged well. It is recommended to arrange it from simplest to the most complex. In this way, the instrument will be more favorable to the respondents to answer. Valid and reliable. The instrument should pass the tests of validity and reliability to get more appropriate and accurate information. Easily tabulated. Since you will be constructing an instrument for quantitative research, this factor should be considered. Hence, before crafting the instruments, the researcher makes sure that the variable and research questions are established. These will be an important basis for making items in the research instruments. Ways in Developing Research Instrument There are three ways you can consider in developing the research instrument for your study. First is adopting an instrument from the already utilized instruments from previous related studies. The second way is modifying an existing instrument when the available instruments do not yield the exact data that will answer the research problem. And the third way is when the researcher made his own instrument that corresponds to the variable and scope of his current study. Common Scales Used in Quantitative Research Likert Scale. This is the most common scale used in quantitative research. Respondents were asked to rate or rank statements according to the scale provided. Example: A Likert scale that measures the attitude of students towards distance learning. Strongly Strongly Items Agree Disagree Agree Disagree There would be difficulty in communicating our concerns to our teacher. There would be many distractions when learning at home than in school. 17 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 Semantic Differential. In this scale, a series of bipolar adjectives will be rated by the respondents. This scale seems to be more advantageous since it is more flexible and easy to construct. Example: On a description of an active student in school activities. Pleasant 5 4 3 2 1 Unpleasant Enthusiastic 5 4 3 2 1 Not Enthusiastic Competent 5 4 3 2 1 Incompetent Another important consideration in constructing a research instrument is how to establish its validity and reliability. Types of Validity of Instrument Face Validity. It is also known as “logical validity.” It calls for an initiative judgment of the instruments as it Validity “appear.” Just by looking at the instrument, the researcher decides if it is valid. A research instrument is considered valid if it Content Validity. An instrument that is judged with measures what it content validity meets the objectives of the study. It is done supposed to measure. by checking the statements or questions if this elicits the needed information. Experts in the field of interest can also When measuring oral provide specific elements that should be measured by the communication instrument. proficiency level of students, speech Construct Validity. It refers to the validity of performance using instruments as it corresponds to the theoretical construct of rubric or rating scale is the study. It is concerning if a specific measure relates to more valid than other measures. students are given multiple choice tests. Concurrent Validity. When the instrument can predict results similar to those similar tests already validated, Validity also has it has concurrent validity. several types: face, content, construct, Predictive Validity. When the instrument is able to concurrent, and produce results similar to those similar tests that will be predictive validity. employed in the future, it has predictive validity. This is particularly useful for the aptitude test. Reliability of Instrument Test-retest Reliability. It is achieved by giving the Reliability refers to same test to the same group of respondents twice. The the consistency of consistency of the two scores will be checked. the measures or results of the Equivalent Forms Reliability. It is established by administering instrument. two identical tests except for wordings to the same group of respondents. Internal Consistency Reliability. It determines how well the items measure the same construct. It is reasonable that when a respondent gets a high score in one item, he will also get one in similar items.

Its uniqueness from other research designs was also described. Remember that experimental research design controls or manipulates the independent variable. This is done by applying particular conditions or treatments or what is called research intervention. In this lesson, the focus is on how to describe your research intervention in your research paper. What’s New Group exposed in Group exposed in usual condition special condition Usual Tutorial Program Special Tutorial Program How is the research intervention conducted in this study? _____________________________________________ _____________________________________________ _____________________________________________ _____________________________________________ _____________________________________________ https://bit.ly/2YleQqq _____________________________________________ _________________________________________________ _____________________________________________ _____________________________________________ 22 Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 What Is It Nature of Research Intervention In experimental research, the researcher decides the nature of intervention or treatment. Intervention pertains to what is going to happen to the subjects of the study. This decision covers who will receive the intervention and to what extent it will be applied to them. For example, in a study of determining the effects of special tutorial program to learners’ at risk of failing (LARF), researcher decides the group of LARF who will receive intervention. In this example, a special tutorial program is the research intervention. Furthermore, the extent to which the program will be administered to the learners is determined. Steps in Describing the Research Intervention Process A section that explains the details of research intervention is added in the research paper if it is an experimental design. In this section, the procedure of research intervention is explained clearly. Write the Background Information. It is an introductory paragraph that explains the relevance of the intervention to the study conducted. It also includes the context and duration of the treatment. Describe the Differences and Similarities between the Experimental and Control Group. State what will happen and what will not both in the experimental and control groups. This will clearly illustrate the parameters of the research groups. Describe the Procedures of the Intervention. In particular, describe how will the experimental group receive or experience the condition. It includes how will the intervention happens to achieve the desired result of the study. For example, how will the special tutorial program will take place? Explain the Basis of Procedures. The reason for choosing the intervention and process should clear and concrete reasons. The researcher explains why the procedures are necessary. In addition, the theoretical and conceptual basis for choosing the procedures is presented to establish the validity of the procedures.

You can now identify the steps you are going to undertake in your actual gathering of data. In this lesson, three phases in data collection will be presented so that you can clearly plan your data collection procedure in your current research. What I Need to Know Quantitative Data Generally, data are any pieces of information or facts that people have known. Once these data answers the research problem, it becomes helpful to research. When research data appears to be measurable in the numerical form, it is considered quantitative data. However, some qualitative data can also be useful to quantitative research once it is given a numerical value. For example, if you study about adjustment experiences of students to distant learning, if it is categorized and numbered accordingly, then it can be quantified during analysis. Techniques in Collecting Quantitative Data The following are the common quantitative data gathering technique. Each technique corresponds to specific instrument which will be further discussed in Module 5. Observation. It is gathering information about a certain condition by using senses. The researcher records the observation as seen and heard. This is done by direct observation or indirect observation by the use of gadgets or apparatus. An observation checklist aid the researcher in recording the data gathered. Survey. Data gathering is done through interview or questionnaire. By means of questionnaire you use series of questions or statements that respondents will have to answer. Basically, respondents write or choose their answer from given choices. On the other hand, interview is when you ask respondents orally to tell you the responses. Since you are doing quantitative research, it is expected that responses have numerical value either it is nominal or ordinal in form. Experiment. When your study is an experimental design, it was already discussed in the previous lesson that it would use treatment or intervention. After the chosen subjects, participants, or respondents undergone the intervention, the effects of such treatment will be measured.

Neglecting to clarify the collection procedure would result in acquiring inaccurate data that will make you research study invalid. Hence, the data collection procedure is given meticulous attention to gather appropriate data. You are making sure that data you will gather answers to your research questions. The data gathering procedure is presented in a paragraph format in your research paper. Basically, the contents are the steps you are going to follow: (1) before you will gather the data, (2) what to do during the actual gathering of data, and (3) the things to consider after data has been gathered.

It is presumed that you already have a good practice of the learning competencies needed to conduct quantitative research. Your background statistics and probability background will help you plan and choose your data analysis. In planning your data analysis in quantitative research, you also need to consider your research problem, type of data, hypothesis, and scale used in your research instrument. This lesson focuses on designing your data analysis procedure. What I Need to Know Data Analysis Data analysis in research is a process in which gathered information are summarized in such a manner that it will yield answers to the research questions. During quantitative data analysis gathered information were break down and ordered into categories in order to draw trends or patterns in a certain condition. In quantitative research, the numerical data collected is not taken as a whole. In order to understand it better, it is analyze into components based on the chosen research variables and research questions you are going to answer. These numerical data are usually subject to statistical treatment depending on the nature of data and the type of research problem presented. The statistical treatment makes explicit the different statistical methods and formulas needed to analyze the research data. What’s New Activity 1: Statistics Recall Directions: From your previous lessons, recall the following terms in Statistics. Write its definition or description and purpose or function in analyzing data. Fill in the boxes to provide the information about these statistical terms or you may use a separate sheet. Use the table for your answer. 30 Terms Definition or Description Purpose or Function Data Downloaded by Shaira Kim Telebangco ([email protected]) lOMoARcPSD|23736473 Frequency Percentage Mean Standard Deviation Table Figure Parametric Test Non-Parametric Test Correlation Regression What Is It Planning your Data Analysis Before choosing what statistical test is appropriate for your research study it is important to determine what statistical formation is applicable to your current study. In immersing yourself into planning your data analysis, you have to decide what basic descriptive statistical technique you are going to use. Although this technique does not give you the degree of association or effect between variables, this will help you to code and simply tabulate your data. Descriptive Statistical Technique provides a summary of the ordered or sequenced data from your research sample. Frequency distribution, measure of central tendencies (mean, median, mode), and standard deviation are the sets of data from descriptive statistics. Inferential Statistics is used when the research study focuses on finding predictions; testing hypothesis; and finding interpretations, generalizations, and conclusions. Since this statistical method is more complex and has more advanced mathematical computations, you can use computer software to aid your analysis. You also have to identify types of statistical analysis of variable in your quantitative research. A univariate analysis means analysis of one variable. Analysis of two variables such as independent and dependent variables refers to bivariate analysis while the multivariate analysis involves analysis of the multiple relations between multiple variables. Furthermore, selecting what test to use is basically done by identifying whether you will use parametric test or non-parametric test. As these were already discussed in your Statistics and Probability subject, a summary of what to consider is presented below: Points to Consider Type of Test Interval or Ratio Parametric Tests Scale Ordinal or Nominal Scale Non-parametric Tests 30 or more per group Parametric Tests Sample Size Fewer than 30 Non-parametric Tests Normal Distribution Parametric Tests Distribution of Data Data deviates from Normal Non-parametric Tests Distribution 31 In addition, in choosing statistical techniques in quantitative research, the purpose or objective of the research study should be considered.

Types of quantitative research are descriptive, correlational, ex post facto, quasi-experimental, and experimental research. Population refers to all the members of a particular group relevant to the research. Sample is a part of the population that serves as a representative. Sample are chosen through sampling which is a process of selecting of who will participate. The usual sampling procedures in quantitative research are simple random sampling, stratified random sampling, cluster sampling, and systematic sampling. Research Instrument refers to the tools used in research for the purpose of gathering the data. Common scales used in quantitative research are Likert Scale and Semantic Differential. It is important in quantitative research to use valid instruments. Validity refers to the appropriateness of the research instrument. Types of validity are face, content, construct, concurrent, and predictive validity. The consistency in research findings provided by instruments refers to reliability. Types of reliability are test-retest, equivalent forms, and internal consistency. For quasi-experiment and experimental research designs, intervention is applied in order to know who will receive the intervention and to what extent. Data gathering in quantitative research usually observes survey, observation, and experiment. There are three phases in data gathering of research that need to be presented in the research paper: before, during, and after procedures. Data Analysis is a process in which gathered information are summarized in such a manner that it will yield answers to the research questions. There are two major statistical technique in data analysis, these are descriptive and inferential statistics. Downloaded by Shaira Kim Telebangco ([email protected])
