Andy is curious as to whether extraversion has an impact on someone's annual earnings. He asked a sample of 100 people (n = 100) about their extraversion and annual income. Then, he does a correlation with alpha =.05, two-tailed, and discovers a significant positive correlation between an individual's extraversion and their yearly pay, with the following results: r(98) =.50, p >.05, r2 =.25, and a large effect size. He comes to the conclusion that persons with lower degrees of extraversion make more money annually. What are four problems with this study or the findings? How can we fix each issue?
