I'm aiming to run a linear regression for some data so I'm testing assumptions. I have a few scatterplots that I'm finding it hard to read. It looks somewhat linear but I can't tell whether they violate the assumption of linearity or not. Dependent variable is on the Y axis in all examples.
The relationship between your variables seems to be very weak. There is possibly a linear relationship in the first plot but I'm very unsure about the other two.
It would he really good if you could give us some more context. What are the x values representing? What's the response? What values does it take (I just see 0s on the side)?
