Interpret the Slope

Interpret the Slope

For every one hour increase, our model predicts a 6 increase in the score on the test.

Interpret the Y Intercept

If a student studies for 0 hours, they will receive a score of 45.

Interpret R²

78% of the score can be attributed to the linear relationship with the hours studies.

Interpret R

.882, the strength of the plots to the line is strong, positive, and a linear relationship between study hours and the score.

Interpret the Residual Plot

A linear graph is appropriate because the plots are random and there are no distinct curves.
