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 3Q Max
-86.90 -26.28 -7.68 22.52 123.74
Coefficients:
Estimate Std. Error t value Pr(>|t|)
(Intercept) 29.430 6.248
