Document Summary
Sampling can be done on: individuals, social artifacts, groups, organization. Population: conceptualizing the population that want to study. Study population: the actual set or list of the population. Sample: the units actually selected from the study population. Statistic (sample description): numerical description (such as mean) of variables (such as age, sex etc) calculated from observations on the sample. Parameter (population estimate): numerical estimation of variables believed to represent the unmeasured population based on observations from the sample. Non-purposive (random) 4: snowball, maximum variation, theoretical construct, critical case, typical case, simple random. Every nth item is selected: stratified. Identify whether it is in a subgroup or not. Is epsem: the sample has an equal probability of being selected. Allow estimates of the entire population base on the population of a few. When researchers are interested to study a specific thing or group. When researchers are not interested in making generalization.
