Subjective Deep Controlled Valid Generalizable Descriptive Reliable Single Inferential Objective Holistic Case Outcome- Specific Analysis oriented Naturalisti Basic c Qualitative Research  Quantitative Research The systematic empirical investigation of observable phenomena using statistical, mathematical or computational techniques. The objective of quantitative research is to develop and employ mathematical models, theories and/or hypotheses pertaining to phenomena. Characteristics of Quantitative Research  The research aims for objectivity and is separated from data. Seeks accurate measurement and analysis of target concepts. Objective Prior to proposing a conclusion or solution to a problem, data are gathered beforehand. It is not based on mere guesses or intuitions.  Tools such as questionnaires or computer software are used to collect numerical data Large population yields more reliable Larger data, but principles of random sampling must be strictly followed. Sample Size The overarching aim is to classify features, count them, and construct statistical models in an attempt to explain what was observed.  Given its high reliability, QR can usually be repeated or replicated to confirm or to verify the correctness of the results in another setting Replicated or Repeated Result of repeated research would yield to higher validity of findings  Data are in the form of number and statistics, often organized and presented using tables, Numerical graphs, charts, figures, or Data other non-textual forms that consolidate large numbers of data to show trends, relationships or differences among variables.  Research paper can be used to generalize concepts more widely, predict future results, or investigate causal Future relationships. Future scenarios of the study may Outcomes be formulated using complex mathematical calculations and with the aid of computers, thus, predicting, future outcomes. Strengths and Weaknesses of Quantitative Research  Strengths of Quantitative Research  Allows for a broader study, involving a greater number of subjects, and enhancing the generalization of the results;  Allows for greater objectivity and accuracy of results. Generally, quantitative methods are designed to provide summaries of data that support generalization about the phenomenon under study. Strengths of Quantitative Research  Applying well -established standards which means that the research can be replicated, and then analyzed and compared with similar studies;  You can summarize vast sources of information and can make some comparisons across categories and over time; and Personal bias can be avoided by keeping a 'distance' from participating subjects and using accepted computational techniques  Weaknesses of Quantitative Research  Quantitative research can be costly, difficult and time-consuming  QR requires extensive statistical treatment, requiring stringent standards, more so with the confirmation of results. When ambiguities in some findings surface, retesting and refinement of the design call for another investment in time and resources to polish the results.  Quantitative method also tend to turn out only proved or unproven results, leaving little room for uncertainty, or grey areas. For the social sciences, education, anthropology and psychology, human nature is a lot more complex. Kinds of Quantitative Research Designs  RESEARCH Quantitative Qualitative Experimental Non-Experimental Descriptive True Quasi- Pre- 1.

One- Group Post-test Only Design - a single group of individuals is measured on some dependent variable after an intervention has taken place. Example: Modular Learning: Its Effect on the Academic Performance of SHS Students Single Interventi group Post test on  True Experimental Design Types 2. Two Groups Post-test Only Design Example: Modular Learning: Its Effect on the Academic Performance of SHS Students Experiment al Control group Group No Interventi Interventi on on Post Test Post Test  2.Pre- Test Post-test Only Design Example: Modular Learning: Its Effect on the Academic Performance Experiment of SHS Students al Control group Group Pre-Test Pre-Test No Interventi Interventi on on Post Test Post Test  -does not Experimenta-treatment is Control Group receive any l Group applied treatment Types of Experimental Research  Quasi Experimental Design -this kind of research is almost the same as that of True Experimental Design. The only difference is the absence of random assignment of subjects to other conditions. Example: “The Effects of Remedial Program to Beginners” Non- Experimental Research Design  The researcher observes the situation or phenomena as they occur naturally and no external variables are introduced.  Variables are not deliberately manipulated nor is the setting controlled  Mainpurpose is to observe, describe and document aspects of a situation as it naturally occurs  Descriptive Research Design deals with the nature, characteristics, and components of the population or phenomena manipulation of variables or search for cause and effect is not applicable determine the frequency with which it occurs and to find general attributes of the presently existing situation. Descriptive Research Example Factors Affecting the Academic Performance of Senior High School students of San Isidro National High School Attendance Family Financial Support Working Student Environment  Types of Descriptive Research Design  Survey- used when the researcher intends to provide a numeric description of trends, attitudes, or opinions of a population by studying sample pop.  Correlational  Ex-Post Facto Research Design – investigates causal relationships  Correlational Research investigates relationships between two variables measures the degree of their relationship or association Example: Grade in Statistics and academic Performance in Practical Research 2  Types of Correlational Research 1. Positive Correlation An increase in one variable leads to the increase of the other variable. A decrease in one variable will also decrease in the other variable Example: Family income and daily allowance Number of hours studying and test scores  Types of Correlational Research 2. Negative Correlation If there is an increase in one variable, the second varible will show a decrease and vice versa. Example: Age of a carabao and its performance Number of children and food serving  Types of Correlational Research 3. No Correlation A change in one variable may not necessariy see a difference in the other variable. Example: Number of hours spent in studying and height of the students  Types of Correlational Research 2. No Correlation Example The relationship between number of hours playing online game and General Weighted Average (GWA) number of hours playing online game General Weighted Average (GWA) Thank you!
