The underlying question when comparing treatments is usually whether an individual would do better with treatment X than they would with treatment Y. But there are often practical and theoretical problems in giving people both treatments and comparing the data. This paper presents the use of propensity score matching as a methodology that can be used to compare the effectiveness of different treatments. The method is applied to answer two questions: (1) “Should examinees take a college admissions test near or a few years after graduation?” and (2) “Do accommodated students receive an unfair advantage?” Data from a large admission testing program is used.
