The differences between univariate and bivariate frequency distribution are :

Univariate Frequency Distribution :

Univariate Frequency Distribution

- When data is classified on the basis of single variable, the distribution is known as univariate frequency distribution.
- It aims to make description about the particular variable.
- It is also known as one-way frequency distribution.
- Ex : Height of students in a class.

Bivariate Frequency Distribution :

- When the data is classified on the basis of two variables, the distribution is known as bivariate frequency distribution.
- It aims to determine the empirical relationship between the two variables.
- It is also known as two-way frequency distribution.
- Ex : Height and weight of students in a class.
