Homogeneity of variance (HOV) is a major assumption underlying the validity of many parametric tests. More importantly, it serves as the null hypothesis in substantive studies that focus on cross- or within-group dispersion. Despite a widely acknowledged need for testing HOV, very few textbooks give adequate coverage on the topic, and many HOV…
