Document Summary

You want to get a subset of the population which is called a sample. Everybody needs a random chance to be selected. Example: pie (you don"t need to eat the whole thing to know what it tastes like) Error is reduced by size of sample - bigger the sample, better it is. Target population: entire set of people sharing the characteristic of interest. Accessible population: a portion of the target population that can be recruited to participate. Sample: individuals selected to be in the study. Sampling frame: listing of accessible population from which you"ll draw your sample (phone survey - book is sampling frame) Inferential statistics are to generalize from your sample to your population. Accessible population: people that could be recruited from your study (some may be ill or on vacation, that"s why we have this) Sample: from those, you"re randomly selecting your sample. The people selected to be in your study.
