Hi, so I’m doing a multiple regression for my uni project and I’ve come to a difficulty. This is what my scatter graph looks like. I’m trying to check for linearity and homostasticity or whatever the word is. I have checked all my data and it all makes sense but I’m not sure why it’s looking like this. Is it because for the X value they have to be in the 1-5 groups and there is no decimal numbers? Is there something wrong that I have done?
