CHAPTER III Chapter Overview Chapter III is your thesis or project “recipe”. You describe the steps you took to conduct your research or designed your project. How detailed should it be? The reader should have enough information that he/she could replicate your research with the same or similar population and arrive at the same results. Introduction of Chapter 3 This chapter showcases the research methods utilized in the study. It also provides sufficient background of the research environment and the chosen respondents. Moreover, it describes and discusses the instruments used to gather the necessary data. The techniques and processes used in collecting and analyzing data are also presented systematically. Lastly, the research ethical considerations are clearly discussed to ensure proper conduct of the study.

Teachers, students, administrators, etc.) Job analysis Documentary analysis Public opinion surveys Community surveys Interrelationships Case studies Causal comparative Correlational studies Developmental Studies Growth studies Trend studies Model or system development Experimental Studies True experimental designs Quasi-experimental designs Pre-experimental designs Experimental Studies Pre-experimental/non-experimental design – follow basic experimental steps but fail to include a control group Experimental Studies True experimental designs - the researcher randomly assigns test units and treatments to the experimental groups Experimental Studies Quasi-experimental designs – no randomization Example: You hypothesize that a new after-school program will lead to higher grades. You choose two similar groups of children who attend different schools, one of which implements the new program while the other does not. Data Gathering Procedures Instrument development Instrument description Validity Reliability How will you get the information? Self-administered survey questionnaire Mailed Online Ask in person Ask ov er the phone Data Gathering Procedures Interview • Face to face • Open-ended • Follow-up questions Observation (Ethnographic) • Watching • Listening • Recording • Nonparticipatory Instrument Validation Does the instrument measure the constructs we intend to measure? Is the instrument reliable? If we retest the subjects with the same instrument over a period of time (with no treatment in between), will they respond the same? Instrument Validation Is the instrument valid? Does it measure what you want it to measure? Population Describe the subjects of your study. What characteristics do they share that includes them in your population of interest? Will you include all members of the population in your study? What is the total number? (N) Sampling Is the size of our population so big that a census is too costly, or will take too much time? Sample the population Random Stratification Proportional Purposive Sample must be representative of the population Sampling Random Sampling - each individual is chosen entirely by chance and each member of the population has an equal chance Stratification - the total population is divided into smaller groups or strata to complete the sampling process. The strata is formed based on some common characteristics in the population data. Sampling Proportional - the investigator divides a finite population into subpopulations and then applies random sampling techniques to each subpopulation Purposive - also referred to as a judgmental or expert sample; the deliberate choice of a participant due to the qualities the participant possesses Data Analysis Procedures Statistical procedures (ie. use of SAS, SPSS, or another analysis software program) Descriptive Inferential Qualitative – transcription of interviews (coding, categorizing, etc.) Use of specialized procedures Analysis Software Program SPSS - Statistical Package for the Social Sciences SAS – Statistical Analysis System Sample Chapter 3 https://drive.google.com/file/d/10AOX0aF1uJGKH3QPrIWJveswKU2DOOZ/view?usp=sharin g
