3. CHAPTER III Research Design Research Locale Respondents of the Study Sampling Design Research Instrument Reliability and Validity of the Research Instrument Data Gathering Procedures Statistical Treatment of Data [email protected]

4. OBJECTIVES To present the different types of research design To determine the samples of the study To discuss the reliability and validity of the research instrument To identify the statistical treatment of data – based form the research problem. [email protected]

5. Research Design Refers to the scheme or plan of action for meeting the objective. A set of instructions for the researcher to gather data and analyze data in certain ways that will control who and what are to be studied. (Blink, 2014). [email protected]

6. Thus, the choice of design is made when the question is finalized. [email protected]

7. Research Design A research design is a general plan or strategy for conducting a research study to examine specific testable research questions of interest. ( Lavrakas , 2011) [email protected]

8. The researcher’s plan How the study will be conducted. Type of data that will be collected The means to be used to obtain these data. [email protected]

9. Research Design The nature of the research questions and hypotheses, the variables involved, the sample of participants, the research settings, the data collection methods, and the data analysis methods are factors that contribute to the selection of the appropriate research design. [email protected]

10. Research Design Thus, a research design is the structure, or the blueprint, of research that guides the process of research from the formulation of the research questions and hypotheses to reporting the research findings. In designing any research study, the researcher should be familiar with the basic steps of the research process that guide all types of research designs. Also, the researcher should be familiar with the problems . [email protected]

11. Quantitative Research Designs [email protected]

12. Quantitative Research is sub-divided into two Major Types Experimental Research Design Non - Experimental Research Design True Experimental Quasi- Experimental According to Purpose According to Time Descriptive - Survey Correlational Longitudinal Cross-Sectional [email protected]

13. Experimental Research Design deals with CAUSE and EFFECT relationships Utilizes the methods of difference research principle Uses two sets of variables. The first set acts a constant which you use to measure the differences of the second set. [email protected]

14. Experimental Research Designs Experimental Designs Methods used to collect data in experimental studies Types of Experimental Designs True Experimental Research Design Quasi-Experimental Research Design [email protected]

15. Aims to determine causal relationships among variables 1. True Experimental Research Design Relies on statistical analysis to approve or disprove a hypothesis Considered as the most accurate type of experimental design Conducted with or without a pre-test Involves a control group and a test group Variable Manipulation Random selection of participants Conducted in a controlled setting Intervention is present [email protected]

16. Control Group Test/Experimental group True Experimental Research Design THE EFFECT OF CLASSICAL MUSIC ON ACADEMIC PERFORMANCE OF STUDENTS Constant/Regular No Intervention No Music Intervention Classical Music Frequency Music Volume Variable Manipulation [email protected]

17. Control Group Test/Experimental group True Experimental Research Design THE EFFECT OF CLASSICAL MUSIC ON ACADEMIC PERFORMANCE OF STUDENTS No Intervention No Music Intervention Classical Music 80% 98% Playing classical music while studying has a positive effect on the students’ academic performance.

18. 2. Quasi- Experimental Design aims to determine a causal relationship among variables Involves conduct of pretest and posttest Conduct in a controlled setting Respondents are not randomly assigned Intervention is present Bears resemblance to true experimental research but – different Variable manipulation [email protected]

23. Non-Experimental Research Design [email protected]

24. DESCRIPTIVE Non-Experimental Research Design Content Analysis Case Study Survey [email protected]

25. Descriptive Research Design A research method that describes the characteristics of the population or phenomenon studied. Primarily focuses on describing the nature of a demographic segment: focuses more on what of the research subject. [email protected]

26. Characteristics of Descriptive Research Design Describes a particular phenomenon and get the general overview of it. Aims to generalize the result Works with large sample size Normally collects quantitative data Variables are uncontrolled. [email protected]

27. DESCRIPTIVE RESEARCH A purposive process of gathering, analyzing, classifying and tabulating data [email protected]

28. DESCRIPTIVE RESEARCH Making adequate and accurate interpretation about such data with or without the aid of statistical methods. [email protected]

29. SURVEY A fact finding study with adequate and accurate interpretation. Use to collect demographic data - Demographic data pertains to the characteristics of human person. (examples age, sex, family income, interest, attitudes and the like) [email protected]

30. Non – Experimental Research Design- Descriptive According to Purpose SURVEY RESEARCH Done to gather evidence on people’s knowledge, opinions, attitudes and values on various issues and concerns. Make use of questionnaires, interviews and surveys. Variables are not controlled/manipulated No intervention is applied [email protected]

31. ARE YOU IN FAVOR OF MASS TESTING? SURVEY RESEARCH Come up with conclusions Analyze and interpret tallied data Record and tally the responses RESPONSIBILITIES N o INTERVENTION YES NO 10 out of 40 respondents = 25% 30 out of 40 respondents = 75% Conclusion Majority of the respondents are not in favor of MASS TESTING . [email protected]

32. Case Study Involve a more in-depth analysis of an individual or smaller audience A comprehensive detailed and in depth study and analysis of an individual, institution, group or community. Must be comprehensive and detailed [email protected]

39. CROSS-SECTIONAL Involves gathering data at a single point in time According to Time Focuses on the same set of variables Comparisons are made across variables of interest Identifying the spending Trends between Men and women in their 30’s Women tend to spend more money than men Spending trends between men and women 20’s 40’s 50’s 60’s [email protected]
