Statistical independence has nothing to do with our conversation, which is about designing an appropriate set of comparator groups to enable valid inference about the hypothesis.
I’m afraid I don’t have time to continue a discussion where we have to pretend that the authors - who have identified sodium as a confounder for their hypothesis - actually wanted to study sodium.
- 4death4 3y agoStatistic independence has everything to do with it. If your control and treatment groups are not independent, you can’t differentiate a case where both groups experience an effect vs. both groups experiencing no effect. Please explain how that would work in your experiment.
