Question

A researcher is studying the effect of 10 different variables on a critical measure of business performance. A multiple regression analysis including all 10 variables is performed. What criterion could be used to eliminate 1 of the 10 variables

Answer 1

Largest p value

Explanation:

The p value is basically used to check if an effect is in existence. A high p value shows that the evidence is weak and cannot be used to say an effect exists.

A p value that is greater than 0.05 is considered to be large and it shows weak evidence against H0, the null hypothesis.

Therefore of the 10 variables, we can use the criterion of largest p values to eliminate one of the variables.
