Document Summary

Population- group you want to generalize to and the group you sample from in a study. Theoretical population- former population who you want to generalize to. Accessible population- latter population population you can get access to. Sample-actual units you select to participate in your study. Sampling- process of selecting units (ie. people, organizations) from a population of interest so that studying a sample you can generalize results to population from which units were chosen. External validity- degree to which conclusions in study would hold for other persons in other places and at other times. Refers to approximate truth of conclusions that involve generalization generalizability- degree to which study conclusions are valid for members of population no included in study sample. 1. sampling model- model for generalizing in which you identify your population, draw a fair sample, conduct your research and finally generalize results to other population groups ( population-draw.
