Question
64. A researcher believes that part of college students' success in school is attributed to their personality type. Her research hypothesis is that college students with Type B personalities will endure frustration in an academic assessment better than students with Type A personalities. She obtained a convenience sample of 40 volunteer college students and classified each person as having either Type A or Type B personality. Next, she sent the volunteers individually to a lab where they were frustrated by a confederate experimenter who asked them to solve 10 anagrams that were unsolvable. Then the confederate experimenter gave the volunteers a new set of 10 anagrams that did have valid solutions and timed how long it took each of them to solve these anagrams (in minutes). The following data was obtained:
E) Name the dependent variable and identify the scale of measurement for the DV.
F) Did the IV have a statistically significant effect on the DV? How do you know?
