"*What is the impact of social media campaign in the number of votes received by a candidate?"* This research question is intended to what type of research design? **A.Historical Research Design C. Descriptive Research Design** B. 4. **The topic "*Socioeconomic characteristics of residents of a community"* is a research topic that must entail to what type of research design?** A. **Historical Research Design C. Descriptive Research Design** B. **Correlational Research Design D. Experimental Research Design** 5. **What is the type of research design where in it looks on the cause-effect relationship and how it affects a variable?** A. **Historical Research Design C. Descriptive Research Design** **B. Causal Research Design D. Experimental Research Design** **RESEARCH DESIGN** **- is a plan that represents how the researcher intends to study an empirical question.** **(Johnson and Reynolds, 2012)** - **It encompasses the entire research process ­-- from the formulation of the research question, the review of related literature, the development of the framework, and the selection of data gathering and analysis techniques.** **QUANTITATIVE RESEARCH DESIGNS** - **DESCRIPTIVE QUANTITATIVE RESEARCH DESIGN** - Uses questionnaires and interviews to gather data about a group of people. - If one intends to empirically present the traits and characteristics of a target population, utilize a descriptive research design. - **CORRELATIONAL QUANTITATIVE RESEARCH DESIGN** - Looks into the degree of association between variables. It considers the extent to which differences between variables are related to the differences in another variable or variables. - It is used to establish or explore relationships, associations, or interdependence between two or more aspects of a situation. (Kumar 1996) - The researcher is trying to find out if there is a relationship between student's performance in statistics and student's absences. - **EXPERIMENTAL QUANTITATIVE RESEARCH DESIGN** - One where a group of respondents are randomly selected to undergo a particular researcher-imposed treatment to determine the effect of such treatment. **Example:** - **CAUSAL QUANTITATIVE RESEARCH DESIGN** - Looks into the cause-and-effect relationships between variable. **Example:** - **HISTORICAL QUANTITATIVE RESEARCH DESIGN** - Makes use of historical data to predict the behaviour of a variable. - Describing and examining past events to better understand the present and to anticipate potential effects on the future. **DESCRIBING SAMPLE SIZE AND SAMPLING PROCEDURES** **[Sample]** \- is a selection of respondents for a research study to represent the total population. **SLOVIN'S FORMULA** ***When to use Slovin's Formula?*** \- If a sample is taken from a population, a formula must be used to take into account confidence levels and margins of error. ***How to use Slovin's Formula?*** **Example:** A researcher plans to conduct a survey. If the population of the Senior High School Department is 5,000, find the sample size if the margin error is 0.05%. n= 5000/(1+5000.0.05^2^) n= 5000/(1+5000.0.0025) n= 5000/(1+12.5) n= 5000/13.5 n= 370.37 or approximately 370 Now, the question is how are you going to select these 370 out of 5,000 which is the total population? Who are these 370 respondents? How are we going to find them? **ANSWER:** For you to determine who arethese 370, you will use one sampling procedure. So out of 5,000 you have to choose 370 respondents only. To choose these 370 respondents, use the following sampling procedures. **MARGIN OF ERROR** **-** is the allowable error margin in research. A confidence interval of 95% gives a margin of error of 5%; a 98% gives a margin of error of 2%; a 99% confidence interval gives a 1% margin of error. ***[MISSION 2]*** **Instruction:** Using the Slovin's Formula, solve for the following statement. Show your solution inside the box. ***"A group of researchers will be conducting a study about the learning styles of the Grade 12 Senior High School Students, with a total of 6,500 students, find the sample size with 5% margin error. And identify the appropriate sampling procedure to be used."*** **[Sampling]** \- is a formal process of choosing the correct subgroup called a sample from a population to participate in a research study. **TWO COMMON TYPES OF SAMPLING PROCEDURE** - **Most common used is** - ***Simple random sampling*** - **Most common used is:** - ***Purposive sampling*** - **Research Method/s or Design Used** - Research Flow - Research Respondents - Research Environment - Research Instruments - Sources of Data - Data-gathering Procedures - Statistical Treatment of Data - Scoring Procedures **Chapter 3** **RESEARCH METHODOLOGY** The process used in this study will be explained in this section. Categorically, it expounds the research method used, research flow, research respondents, research environment, locale of the study, research instruments, sources of data, scoring procedures. **Research Method/s Used** The study used a Descriptive Quantitative method or design. Descriptive describes the characteristics of the population or the phenomenon that is being studied. Primarily focuses on describing the nature of a demographic segment without focusing on "why" a certain phenomenon occurs. While Quantitative attempts to collect quantifiable data to be used for statistical analysis of the population sample. Hence, the nature of the variable of their behavior is not in the hands of the researcher. **Research Respondents** The Respondents of this study are the selected Grade XII students-afternoon session in Asian Learning Center- Pajo Campus in school year 2019-2020. Out of 645 total number of students from different strands in afternoon session, the researcher have come up with the total of 160 respondents. The researcher used a Slovin's formula with the use of online calculator with the confidence level of 85% with the plus 5 margin of error. This means 160 or more measurements/surveys are needed and the real value is within = 5% of the measured survey value. The researcher divided the 160 respondents into 5, the result is 32. Each strand should have 32 respondents, in order to get the total respondents of 160. ***[MISSION 3]*** **PERFORMANCE TASK\ "IDENTIFYING YOUR SAMPLE SIZE"** ***Instructions:\ 1. Using the Slovin's Formula, solve the accurate number of your respondents.\ 2. Identify and explain the type of sampling to be used.\ 3.** Submit your manuscripts to your research teacher.* ***Total \# of respondents:*** -------------------------------- ------------- ***Margin of error:*** ***0.05%*** ***Sampling:*** **References:** - ***An introduction to Quantitative Research - Practical Research 2, Torneo, A & Torneo H, 2017*** - [***https://prudencexd.weebly.com/\#:\~:text=%2Dis%20used%20to%20calculate%20the,margin%20of%20error%20(e).&text=%2DIt%20is%20computed%20as%20n,%2F%20(1%2BNe2).&text=%2D%20If%20a%20sample%20is%20taken,levels%20and%20margin%20of%20error***](https://prudencexd.weebly.com/#:~:text=%2Dis%20used%20to%20calculate%20the,margin%20of%20error%20(e).&text=%2DIt%20is%20computed%20as%20n,%2F%20(1%2BNe2).&text=%2D%20If%20a%20sample%20is%20taken,levels%20and%20margin%20of%20error)  **CHECKPOINT:\ Name: [ ] Quarter: [2\ ]Section: [ ] Week: [ 9 ]** **PRACTICAL RESEARCH 2** Directions: Write your answer on a space provided. 1\.
