How to determine the sample size with pre defined degree of
precision?.
Why Sampling?

We come across situations whose where we would like to know
But the factors like time, money, cost and large size of the
population make it almost impossible to go for the complete
enumeration of all the population.

Sampling Theory
Instead we can select a representative or part of the population
(known as sample) & infer about the entire population on the
basis of our knowledge about the sample.
This is the basis of Sampling Theory.
