Bartlett test for equality of variance

a procedure used to determine whether variation across two or more groups is equivalent, this being a critical assumption in analysis of variance and many other parametric methods. The Bartlett test is sensitive to scores that are not from a normal distribution. [Maurice Stevenson Bartlett (1910–2002), British statistician]
