Document Summary
Element the entity on which data are collected. Population the collection of all elements of interest. Target population the population about which inferences are made. Sampled population the population from which the sample is taken. Frame a list of the sampling units for a study. The sample is drawn by selecting units from the frame. Probabilistic sampling any method of sampling for which the probability of each possi- ble sample can be computed. Nonprobabilistic sampling any method of sampling for which the probability of select- ing a sample cannot be computed. Convenience sampling a nonprobabilistic method of sampling whereby elements are se- lected on the basis of convenience. Judgment sampling a nonprobabilistic method of sampling whereby element selection is based on the judgment of the person doing the study. Sampling error the error that occurs because a sample, and not the entire population, is used to estimate a population parameter.
