Multiple regression

Explanation:

With regards to the above, multiple regression can be used to determine one educational background, interest and gender so as to see if there is a variation in terms of individual's annual income as it relates to their educational background.

Multiple regression basically is a mathematical model, which is used when one value is matched with two or more variables.
