These normal populations have a common variance. (Levene’s testcan be used to check this.) How one-way ANOVA test works? Assume that we have 3 groups (A, B, C) to compare: Compute the common variance, which is calledvariance within samples(S2withinSwithin2) orresidual variance. ...
If there is doubt about normality, the better choice is to useLevene’s testorFligner-Killeen test, which are less sensitive to departure from normal assumption. Compute F-test # F-test res.ftest <- var.test(len ~ supp, data = my_data) res.ftest ...
