Green: normal (p ≥ 5%) · Yellow: p < 5%, not significant after correction · Red: significant even after correction · –: test not applicable.
* fewer than 300 draws in the current format: tests still have little power.

How to read the table

The p-value is the probability of a result at least this extreme under pure chance. Below 5%, a single test is usually called “significant”. Because 11 tests run at once, about 0,55 such hits are expected by chance alone; the Holm correction accounts for that. Only a result still below 5% after correction would be a serious hint.
