(a) To estimate the frequencies of the unknown population distribution from sample data.

(b) To facilitate the analysis of data.

(c) To facilitate calculation of different statistical measures.

Types of Frequency Distribution

(i) University Frequency Distribution

(ii) Bivariate Frequency Distribution

(iii) Univariate frequency distribution is of two types:
