MCQs on Sampling Methods

Sampling is defined as a technique of selecting individual members or a subset from a population in order to derive statistical inferences, which will help in determining the characteristics of the whole population. There are various methods of sampling, which are broadly categorised as random sampling and non-random sampling.
