What is homogeneity of variance?
A) It is the assumption that we want to have similar amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be similar.
B) It is the assumption that we do not want to have similar amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be different.
C) It is the assumption that we want to have different amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be different.
D) It is the theory that we want to have similar amounts of observations in each of our conditions. When we have homogeneity of variance, then the number of observations in each of our conditions should be similar.

Homogeneity of variance is the assumption that the variances across groups or conditions are equal or similar. This is important for certain statistical tests, like ANOVA, which assume that variances are equal across groups to produce valid results.
