ANOVA( (one-way analysis of variance; item F) computes a
one-way analysis of variance for comparing the means of
two to 20 populations. The ANOVA procedure for
comparing these means involves analysis of the variation
in the sample data. The null hypothesis H0: m1=m2=...=mk is
tested against the alternative Ha: not all m1...mk are equal.
