Sampling

Abstract

Population in statistics means the whole of the information, which comes under the purview of statistical investigation. Sample is a selected portion of the population. A sample drawn from a population provides valuable information about its parent population. Sampling is a tool, which enables us to draw conclusions about the characteristics of the population after studying only those items that are included in the sample. In this chapter we discuss types of sampling, sampling distributions. The method of determining the size of a sample is discussed.
