Test Levene i Brown-Forsythe za jednakost varijansi
Test Levene i Brown-Forsythe proverava da li dve ili više grupa dele istu varijansu (homogenost varijanse). Levene (1960) je zasnovao test na apsolutnim odstupanjima od proseka svake grupe, a Brown i Forsythe (1974) su ga učinili robusnim na nenormalne podatke centriranjem na medijanu grupe umesto toga.
