The research hypothesis when using ANOVA procedures is that at least one of the group means is significantly different from the others. This is because ANOVA is used to test for differences among multiple groups, and the hypothesis being tested is whether or not there is a significant difference in means between at least one pair of groups. Choice A is incorrect because it only applies to a comparison of two groups. Choice B is incorrect because it assumes that all of the group means are the same, which is not the hypothesis being tested. Choice D is incorrect because it is too extreme and unlikely to be true in most cases.
