What is the difference between univariate data and bivariate data?

Univariate is defined for a single variable while bivariate is for two variables.

Answer: The basic difference between univariate data and bivariate data is that the latter deals with the causes and relationships while univariate data only describes the single variable in it.

Let us go through the various points of difference.

Explanation:

Points of difference between univariate data and bivariate data are in the order:

Univariate data:

1) Involves a single variable

2) Does not deal with causes or relationships.

3) Major purpose is to describe.

4) Sample question:  How many students in the class are males?

Bivariate data:

1) Involves two variables.

2) Deals with causes and relationships.

3) Major purpose is to explain

4) Sample question: Is there a relationship between the number of boys in computer programming and their and scores in mathematics?

Thus, the basic difference between univariate data and bivariate data is that the latter deals with the causes and relationships while univariate data only describes the single variable in it.
