Grading Scale
  • Data Tables - Color Scale

    Cells that are not highlighted indicate a value that is within a half standard deviation of league average (or that an average is not available).

    Cells that are dimly highlighted indicate a value that is between one-half and one-and-a-half standard deviations from league average.

    Cells that are vividly highlighted indicate a value that exceeds one-and-a-half standard deviations from league average.

    Green indicates a generally good deviation. Red indicates a generally bad deviation. Blue indicates a generally neutral deviation (or a deviation of unknown significance).
