Simple Random Sampling Procedure. Simple random sampling is the most basic and common type of sampling method used in quantitative social science research and in scientific research generally. The process for selecting a random sample is shownin Figure 3-1. As for example flipping a coin or die drawing numbers from a hat using random number generators or random number tables. It is important to note that unlike with the strata in stratified sampling the clusters should be microcosms rather than subsections of the population.
A simple random sample is defined as one in which each element of the population has an equal and independent chance of being selected. Subgroups might be based on company size gender or occupation to name but a few. Simple random sampling is defined as a sampling technique where every item in the population has an even chance and likelihood of being selected in the sample. The procedure of selection of a random sample follows the following steps. Many sampling schemes have been developed to achieve this objective. As such it is an equal probability selection method EPSEM.
311 Random sampling Subjects in the population are sampled by a random process using either a random numbergenerator or a random number table so that each person remaining in the population has the sameprobability of being selected for the sample.
Here the selection of items entirely depends on luck or probability and therefore this sampling technique is also sometimes known as a method of chances. Therefore systematic sampling is used to simplify the process of selecting a sample. As such it is an equal probability selection method EPSEM. The procedure of selection of a random sample follows the following steps. Data is then collected from as large a. It is also the most popular method for choosing a sample among population for a wide range of purposes.
