All of the students in Dr. Wright’s psychology class had to conduct their own research study and prepare a report describing it. The instructor, after carefully reading all of the papers, gave one of the following students an A. The remaining three students all got lower grades. Based solely on the information given here, who was the happy student who got an A?
  1. Danielle, whose study with 16 ethnically diverse students confirmed her hypothesis.
  2. Janelle, whose study with 60 private school students on the relationship between IQ and grade point average confirmed her hypothesis.
  3. Lydell, whose report included an in-depth discussion of the methodological flaws which might have contributed to the non-confirmation of his hypothesis.
  4. Tyrell, whose paper was seven pages long, in comparison to the other students’ papers which were at least twice that length.
  5. Not enough information to determine.
Explanation
Answer: D - Since one of the students described got an A, by process of elimination, it had to be Tyrell. Danielle’s study used too small of a sample. Janelle’s study used a biased sample, and Lydell should have worked out his methodology more carefully before conducting the study instead of just acknowledging the deficiencies after the study. On the other hand, just because Tyrell’s paper was shorter does not mean both his study and report were not high quality.
