- Why wouldn't the answer for problem 4 be the members of each household?(33 votes)
- The members of each household receive the same diet, but each household could have a different diet. Since the diet is consistent in the household, the household is the experimental unit.(68 votes)
- Words are slippery. The last question expects as correct answer the households, not their members. Makes me scratch my head and and ironically conclude: "Aha! So it is the households who eat (or not) the kale, not the household members".(9 votes)
- That is a funny point, but the household is the whole of the household members. We were comparing different households as a whole and not a households individual members.
