One of the basic reasons for
undertaking a sample survey is to predict and generalize the results for the
population as a whole. The logical process of drawing general conclusions from
a study of representative items is called induction. In statistics, induction
is a generalization of facts on the assumption that the results provided by an
adequate sample may be taken as applicable to the whole. The fact that the
characteristics of the sample provide a fairly good idea about the population
characteristics is borne out by the theory of probability. Sampling is based on
two fundamental principles of statistics theory viz, (i) the Law of Statistical
Regularity and (ii) the Law of Inertia of Large Numbers.
