A mix of linear regression and analysis of variance. analysis of covariance is responsible for intergroup variance when analysis of variance is performed.
In regression analysis , heteroscedasticity means a situation in which the variance of the dependent variable varies across the data. Heteroscedasticity complicates analysis because many methods in regression analysis are based on an assumption of equal variance.
The Fisher F-test for Analysis of Variance (ANOVA).
The F stat tests the equality of variances. It uses statistical tables for reference and is calculated with F = Variance 1 (max)/variance 2(min).
1- observations are from normally distributed populations. 2- observations are from populations with equal variances.

Compare Standard costing vs variance analysis?"
Analysis of Variance (ANOVA) compares 3 or more means. The t-test would only compare 2 means.
