Answer #1

Hi,

According to the question:

Correlation tells about the linear relationship between two variables while regression tells about the functional form of relationship between two variables in which one variable is a dependent variable while other variables are independent variables.

Consider a multiple linear regression model with 3 independent variables. Then, t test is used to test significance of individual regression of an independent variable while F test is used to test the significance of overall regression, considering all independent variables together.

Thanks!

Conceptual Questions 1.) Relativity tells us that objects should look skinner from an external perspective while they move, but I have never seen that in person. Why is this so?
