Oishi and Schimmack (2010) report that people who move from home to home frequently as children tend to have lower than average levels of well-being as adults. To further examine this relationship, a psychologist obtains a sample of n = 12 young adults who each experienced five or more different homes before they were 16 years old. These participants were given a standardized well-being questionnaire for which the general population has an average score of m = 40. The sample of well-being scores had an average of M = 37 and a variance of s 2 = 10.73.
a. On the basis of this sample, is well-being for frequent movers significantly different from wellbeing in the general population? Use a two-tailed test with a = .05.
b. Compute the estimated Cohen’s d to measure the size of the difference.
c. Write a sentence showing how the outcome of the hypothesis test and the measure of effect size would appear in a research report
