Re: [R] Interpreting coefficients in linear models with interaction terms

Hi, I have very limited (one class and the rest self-taught) statistics background (I am a comparative biology major) working on an independent study. I think that I am beginning to understand: The coefficient SexM is the slope estimate for TestNumber1. If I add the coefficients for the other tw

[R] Interpreting coefficients in linear models with interaction terms

Hi, I am trying to interpret the coefficients in the model: RateOfMotorPlay ~ TestNumber + Sex + TestNumber * Sex where there are thee different tests and Sex is (obviously) binary. My results are: Residuals: Min 1Q Median 3QMax -86.90 -26.28 -7.68 22.52 123.74 Coefficients:
