What Paul and Nancy should do to ensure a fair comparison between all the hives is to d<span>ocument the number of bees as compared to the amount of honey per hive.

The correct answer is "Document the number of bees as compared to the amount of honey per hive".
Explanation:
Choosing a proper criteria to evaluate different populations is one critical step of design of experiments. It is very important that the criteria of evaluation really measures what the researcher is trying to study. In this case, Nancy and Paul want to measure the amount of honey produced by each of the bee hives. Document the number of bees as compared to the amount of honey per hive would be a proper criteria to fairly compare the bee hives. This measure would be a better criteria than just measuring the honey directly because by measuring the amount of honey in comparison to the number of bees, the variable of the amount of bees does not interfere with the data.
