We believe teachers and schools should be graded using the bell curve/ normal distribution; however, we believe they should be ranked by mean . The tie breaker would be the lowest standard deviation.

The max. and min. are extreme outliers
The mean is a good representation of the center of the data
Compare teachers using there z-scores
