Equivalent groups are groups that do not differ in any systematic way before being given the independent variable. This ensures that any differences observed between the groups after the manipulation of the independent variable can be attributed to the variable itself and not to pre-existing differences between the groups. A and D are wrong because equivalent groups do not have to be exactly the same in every way, and they do not necessarily have bimodal distributions. C is also incorrect because equivalent groups can come from the same population.
