Questions

Identify the level of measurement of each variable.

- You may use Stata or a hand calculator to answer this problem, but you must show your work or code in your answer.

AI use is allowed on this and every problem set that is graded check/no check in this class. You should disclose any AI use as a matter of standard professional ethics, but you will not be evaluated on whether or not you used AI.
I encourage you, however, to use AI intelligently: use it like a teaching assistant to help you understand the material, not as a bot to automatically solve the problem set for you. Remember that you will not have access to a chatbot during in-class exams, so the problem sets are your chance to practice.
