Document Summary
The sample you select is dependent on the type of questions you are asking and your approach to the research topic. Sampling is using part of a population (i. e. , sample) to make inferences about, or to make generalizations to, the entire population. Refer to the characteristics or variables in the population being studied. Population is homogenous if the variable in question tends to be similar (think degrees) There are 2 requirements for a sample to be considered random: nothing but chance can govern the selection process, every case must have an equal chance of selection. Population and universe refer to all of the cases you are choosing from. Sampling elements or units of analysis are the source of your information. A sampling frame is a list of all of your elements or units of analysis. Method of choice when well-defined population to draw sample from and then generalize back to that broader population: conform to rules of probability, generalizability important.
