![]() ![]() This method actually takes us back to the methods in Chapter 1 where we compared the means of two groups except that we need to deal with potentially many pair-wise comparisons, making an adjustment to account for that inflation in Type I errors that occurs due to many tests being performed at the same time. It also will test for differences between the OJ-0.5 and VC-2 groups and every other pair you can construct. For example, we might want to know if OJ is different from VC at the 0.5 mg dosage level and these methods will allow us to get an answer to this sort of question. Others feel that it is an important method of addressing detailed questions about group comparisons in a valid way. ![]() ![]() Because this is a shot-gun/ unfocused sort of approach, some people think it is an over-used procedure. This provides information on the source of the overall difference that was detected and detailed information on which groups differed from one another. With evidence that the true means are likely not all equal, many researchers want to know which groups show evidence of differing from one another.
