Document Summary
Research methods and analysis lecture 6 notes, 10/4/16. *job in research proposal not to support what is already known, but to find a gap to fill in with your study. After conceptualizing and operationalizing the variables, * define the population of interest and select a sample* Sampling rationale and goals: population: the complete set of individuals or objects that the investigator is interested in studying. Problem: the populations we wish to study are almost always so large that we are unable to gather info from every case. Solution: choose a sample a carefully chosen subset of the population and use info gathered from the cases in the sample to generalize the population: goal: choose a representative sample. Rep. sample has the same (or almost the same) characteristics as the population. Allows us to link the known characteristics of the sample to the unknown characteristics of the population.
