I have created a multiple regression model that checks if final result is explained by following predictor variables:
Time spent studying Class attendance (%) Cash spend on extra materials and classes etc.
Now I have a group of 50 boys and a group of 50 girls. I run my model for each gender independently. Can I compare coefficient of (for example) Class attendance for boys with coefficient of same variable for girls and say:
"Boys final results are less dependent on their class attendance than girls?"
If not how can I compare them?
