Population and Sampling
Population and Sampling
You cannot study every student. You study some of them. This chapter explains the difference between population and sample, and which sampling methods suit action research.
| Step | What it is | Example |
|---|---|---|
| Population | The full group your findings should apply to | All Grade 8 students in your school |
| Sample | The smaller group you actually study | Section A only (40 students) |
| Sampling method | How you chose the sample | Convenience (you teach that section) |
| Reason | Why this method fits the question | The question is about your own students, not all schools |
The entire group of people the researcher wants to draw conclusions about.
The smaller group selected for the study, and the process of choosing them.
Why action research uses these methods instead of random sampling.
Why small samples are usually fine, and the few cases when you need more.
