Referee × club
All clubs refereed by Alberola Rojas, by number of matches. Verdicts tested on the whole database (pairs with at least 5 matches).
Verdict / q-value With hundreds of comparisons, some look extreme by chance. The Benjamini-Hochberg correction accounts for this: a deviation is only called notable if q < 0.05. Otherwise: inconclusive. Inconclusive does not mean "no effect": with 11 matches, only a deviation of about ±1.57 points per match could have been detected.
Verdicts on 5 measures: points, penalties, reds, yellows, fouls. "Descriptive" = fewer than 5 matches, no test.
