Hi!

I'm making multiple regression and has a variable namned RP as an independent/control variable. The RP variable is negative in two models, but in the last model when EDU is added, the coefficient change sign from negative to positve. Why? The table looks like in the table. I also checked for VIF statistics and found the following result.

Thanks in advance!
Best regards,
Kajsa
