Abstract

A "sample" is a miniature representation of a larger group or aggregate. In other words, the sample provides a specimen picture of a larger whole. This larger whole is termed as the "population" or "universe". The procedure of collecting data for each and every unit belonging to the population, which is the aggregate of all units of a given type under consideration, is termed as census. The effort, money and time required for carrying out census will be enormously large. The census is necessary only if information is required for each and every unit in the population under study. Most of the time, it is impossible, difficult or expensive to observe all the elements of a population in order to arrive at a valid conclusion. Moreover, the sizes of populations are often so large that the study of all the units would not only be expensive but also cumbersome and time consuming, for example, the fishery resources in Indian Seas.
