The true statements about one-way ANOVA when there are m groups are: The null hypothesis is that all of the means are the same. The alternative hypothesis is that exactly one mean is different. If we conducted separate tests instead of using ANOVA we would have to do m tests. It is assumed that the variance is the same for each group/category.
