A medical school dean wondered whether students who did better in her medical school became better physicians. To test this, she gathered a sample of medical students in their final year and determined their GPAs. She also administered to each student the Differential Diagnosis Test (DDT). The DDT presents students with 50 diagnostic dilemmas. Each dilemma is considered equivalent and scores on the DDT can range from 0 (no questions answered correctly) to 50 (all answered correctly). What statistical test should the dean use to answer her question?

In this series of questions, there are no headings that tell which flowchart to use. Plus, some gaps occur in the flowchart. For example, if the scenario has two dependent samples with an ordinal-level dependent variable, there is no such test in the flowchart. Tests exist for such situations; they just weren’t covered in this book. So, if a scenario in this series calls for a “missing” test, just write, “No such test in book” as your answer.
