Suppose I wanted to know whether a surprise quiz before themidterm improves your midterm score. Suppose I’m teaching twosections of this class, and I decide to test this by setting asurprise quiz for the first section and not for the second section,and then comparing the average scores of the two sections on themidterm. What assumption(s) would need to hold in order for me toestimate the true effect of a surprise quiz on midterm score inthis manner? Explain.
