AAMC Psych/Soc Section Bank #51

Hello!

How would you reason between the answer choices B, a positive correlation between hunger and inadequate sleep, or C, that there is evidence that inadequate sleep causes hunger..?

These two answers seem almost analogous!

Thank you!

This shows up as #53 for me. There are a few issues with the new AAMC interface if you've previously answered some questions. This is also a question that trips absolutely everybody up!



There are a few reasons B is wrong:
1. Particularly on the MCAT, observational studies yield correlations and experimental studies may give insights to causes (or at least they try to). Answer B is about correlations, while C is about causes.
2. The MCAT also tests linear regression analysis as the main way of determining a linear correlation, and linear regression analysis requires three data points.


I would go with part 1 as far as generalizable lessons from this go: Always pay attention whether a study is experimental or observational.
