SD Score explanation:

Run production is one of the best measures of how a team is performing and how dominant or bad they are.

The formula takes each team’s runs scored and runs allowed totals and how many standard deviations from the league average they are.

Example: 1927 Yankees

The 27 Yankees score 975 runs (1927 AL average was 762 and SD of team runs for the AL was about 115). Take the difference from the league average (975-762=213) and divide by the SD (115), the 1927 Yankees were 1.85 SD above the league average in runs scored.

They allowed 599 runs (the SD in runs allowed for the 1927 AL was about 88.5), which was 163 runs less than the league average. 163/88.5 gives us a 1.84 SD above the league average in runs allowed.

Add 1.85 and 1.84 to get a final SD Score of +3.69 for the 1927 Yankees, which is amazing.
