Interpretations

R-squared An R-squared of ____% indicates that ____% of the variation in y-variable can be accounted for by the x-variable.

Standard Deviation of your residuals 𝒔 𝒆 Standard Deviation of your residuals True y-variable varies from the predicted with a standard deviation of _____ units.

𝑺𝑬( 𝒃 𝟏 ) Standard Error of the slope If we constructed other models based on different samples of __________, we’d expect the slopes of the regression lines to vary, with a standard deviation of about ________ per unit.

Conclusion We are ____ % confident that each (increase in the x-variable) causes (the y-variable to increase/decrease) between ____ and _____ on the average.
