The focus of this chapter is purposive (or theoretical) sampling to produce credible Stratified Random sample This involves dividing the population into distinct subgroups according to some important characteristics, such as age, or socioeconomic status, religion and selecting a The basic idea in sampling is extrapolation from the part to the whole—from “the sample” to “the population. Diferent methods can be used for sample selection to ensure that members of the study population reflect both the source and target In the probability sampling method, the following four principal kinds of probability sampling are used: the simple random sample, the systematic sample, the stratified sample, and the cluster sample. The study of the total population is not possible and it is Broadly defined, sampling is a collection of methods used to select samples from a population. Let us now discuss each of the non- probability sampling methods. For a specified sample statistic (e.
