Fligner

The Fligner-Killeen test: do several groups share one variance?

The third equality-of-variance test beside Levene and Bartlett, and the one that ranks: each group's absolute deviations from its centre are ranked together, turned into normal scores, and compared across groups by a χ² statistic. Ranking is what makes it hold up where the data are neither normal nor free of outliers.
