I should clarify. I am using the term weight and scale, but I now realize this is a relatively poor analogy. What I mean are actually weight (like body mass) and a scale as in a measuring scale like you use in the bathroom. Imagine if you lined people up and measured how heavy they were using four different tools. I selected that answer as correct because, when transposed, SAS was able to solve. Whether or not that’s statistically appropriate, feel free to comment. Yes, I’m looking for the equivalent of a paired t-test, but for four groups. I was under the impression that an anova was the appropriate test. I’m not looking to model the relationship between the four groups, simply evaluate whether or not the scales measure the weights the same. As far as missing data, there are two missing data points for one of the four scales, but the other three are complete. Regards.
