Primary Data

[abhishreshthaa]

The primary data are reliable. However, problem in primary data is its cost, both in term of money and time required for collection.


Primary data are of two types:-


a) Census:- It refers to the collection of data from the entire population. In India population census is taken after every 10 years.


b) Sample:- sampling is an internal part of data collection through surveys. Sampling is used to collect primary data when sources of data are too many to be exhaustively handled. A sample is only representative portion of the population.
