Replace Sulfur by its logarithm, and consider transforming the response Tension. To do this, draw the inverse fitted value plot with the fitted values from the regression Tension ∼ log(Sulfur) on the vertical axis and Tension on the horizontal axis. Repeat the methodology of to decide if further transformation of the response will be helpful.
