Question

How does a bivariate regression model differ from a multiple regression model?

Multiple Choice

• A bivariate regression has only one dependent and independent variable but a multiple regression has one dependent variable and may have many independent variables.

• A bivariate regression has more than one dependent variable and only one independent variable where a multiple regression has one dependent variable and may have many independent variables.

• A bivariate regression has only one dependent and many independent variables but a multiple regression has one dependent variable, but may have many independent variables.

• A bivariate regression has only one dependent and independent variable but a multiple regression has more than one dependent variable and may have many independent variables.

Answer 1

A bivariate regression has only one dependent and independent variable but a multiple regression has one dependent variable and may have many independent variables.

[ explanation:-

the general form of bivariate regression is :-

$y=a+bx$

where, x = independent variable, y = dependent variable.

the general form of multiple regression is :-

$y=b_{1}x_{1}+b_{2}x_{2}+...b_{n}x_{n}$

where, y = dependent variable , x₁,x₂,.......,x_n = independent variable ]
