Levine un Braun-Forsaits tests vienādu varianču pārbaudei

Levine un Braun-Forsaits tests pārbauda, vai divas vai vairākas grupas dala vienādu varianci (variaciju homogenitāti). Levins (1960) izveidoja testu, balstoties uz absolūtajām novirzēm no katras grupas vidējās vērtības, bet Brauns un Forsaits (1974) padarīja to noturīgu pret nenormāliem datiem, centrējot uz grupas mediānu.
