studying the sample we may come up with general characteristics of the entire population under consideration. Types of sampling methods: Probability sampling Probability sampling is a type of sampling that includes random selection. And in order to achieve random selection‚ it must be made sure that different units of population have equal probability of being chosen. Some relevant terms: N = the number of cases in the sampling frame n = the number of cases in the sample f = n/N =
