MMDA Team Report Cards For 2020

Context is so important to analysis. 

Numbers take on new meaning when presented in such a way that they can be interpreted quickly and accurately. Toward that end, I created a league report card that grades each MMDA team in terms of its proficiency across basic categories of component performance.

Grades were determined by standard deviation Z-scoring and then mapping those scores to the familiar report card grading tiers of A, B, C, D and F. A true grade point average could be developed by weighting each of the categories based on significance, but I elected to keep things simple for the first draft.

The TOTAL column places the same weight on each category, i.e. it's an average, and is more of a sorting tool than accurate portrayal of overall quality.
