n. in statistics, a test for the equality of variance. Based on independent normal samples from populations, the null hypothesis is tested as to homogeneity of variance. As a statistical procedure, however, this test is highly-dependent on the normality assumption. Put forward by British psychologist Sir Frederick Charles Bartlett (1886-1969). See Levene Test.
BARTLETT’S TEST: “Homogeniety of variance is the key factor in inferential tests such as Bartlett’s Test and Levene Test.”
