Document Summary
Selection of simple random sampling using lottery method and random numbers. The basic probability sampling method is the simple random sampling. It is the simplest of all the probability sampling methods. It is used when the population is homogeneous. When the units of the sample are drawn independently with equal probabilities. The sampling method is known as simple random sampling (srs). Thus if the population consists of n units, the probability of selecting any unit is 1/n. A theoretical definition of srs is as follows. There are two methods in srs: lottery method, random no. table method. This is most popular method and simplest method. In this method all the items of the universe are numbered on separate slips of paper of same size, shape and color. They are folded and mixed up in a drum or a box or a container. Required numbers of slips are selected for the desired sample size.
