PSYB01H3 Chapter Notes - Chapter 5: Simple Random Sample, Nonprobability Sampling, Stratified Sampling
Document Summary
Sample: a group of units selected from a larger group that is known as the population. Survey research: research in which information is obtained from a sample of individuals through their responses to questions about themselves or others. You can study an entire population of interest by conducting a census: research in which information is obtained through responses that all available members of an entire population give to questions. Unfortunately, this is very time consuming and takes a lot of effort. In behavioural research, it has been found that: Students, disabled persons, the elderly, and adult samples tend to report similar (not identical) levels of happiness. The same is true of men and women, as well as white and african americans. However, in countries around the world, happiness levels are very different. Satisfaction with life is also different across cultures. This means cannot generalize happiness finding from population to population.
