The first model included just thetimeattribute. The model code in R was lm(Performance~ time). The R-square for this model was 37.58%.
The second model included just thecolorattribute. The model code in R was lm(Performance~ color). The R-square for this model was 1.31%.
The third model included both thetimeandcolorattributes. The model code in R was lm(Performance~ color + time). The R-square for this model was 38.89%.
Rank the three models by how much variance they explain in math scores (ie, math performance)?
Most variance explained
[ Choose ] The third model (color and time) The first model (time only) The second model (color only)
Middle variance explained
[ Choose ] The third model (color and time) The first model (time only) The second model (color only)
Least variance explained
[ Choose ] The third model (color and time) The first model (time only) The second model (color only)
