Unsurprising.I did. I think I’ve done it up to the end of last season. You’d imagine that over the course of a number of seasons there would be no statistically significant differences between the figures for the individual refs when refereeing specific clubs. So if a club has an average of 2 points per game over 8 seasons, you would expect individual refs to show figures between 1.8 and 2.2 for games involving that clubs. Maybe 1.75 to 2.25. But there are some spectacular statistical anomalies.
Atkinson is generally OK for all the top six but there's a staggering anomaly for Dean and Arsenal. Their average PPG for all PL games from 2010/11 to 2016/17 is 1.93 but under the 27 games reffed by Dean it's 1.11. That's statistically significant and suggests something's wrong. Oliver's even worse although he's done less games (18 to Dean's 27). Jones an Moss on the other hand seem to significantly favour Arsenal.
Mason significantly favours the rags, with 2.73 PPG and Moss returns 2.53 for them compared to their overall average of 1.99.
All the rest are more or less OK and, believe it or not, Taylor is by far the most consistent across the top 6.
PGMOL needs to use statistics like this to measure referee performance to abolish bias.
