PSYA01H3 Study Guide - Nonprobability Sampling, Stratified Sampling, Systematic Sampling
Document Summary
We have a large population and then we have a subgroup who we observe and/or study sampling. Sampling is selecting a subset of observations from a population of interest. Who do you want to generalize to: the theoretical population. What population can you get access to: the study population. How can you get access to them (how do you find them?: the sampling frame. Who is in your study (who do i end up doing my study on?: the group about whom you want to draw inferences, the subset of the population from which sample is actually drawn, the sample. Sample: the actual list from which sampling units are drawn, the elements available for selection into the sample, subset of study population selected for investigation. Selection can be either probability or non-probability sampling. Biased samples: do not represent the population as a whole.
