Have you ever had a professor give you an assignment, and you didn’t know how to do it but you were too embarrassed to ask?

We shine a light on skipped survey questions, strange placeholder codes (99 kids?!), and how to avoid misinterpreting your results. Turns out, what’s not there can be just as important as what is.
