A personality psychologist is interested in the relationship between extraversion and self-esteem in college students. They run a test to see if you can predict a person's self-esteem score by their score on an extraverted scale. Once they finish, they tell you that extraversion accounted for 35% of the variance in self-esteem scores, but they do not provide any other details about their analysis or their study. Given this information and assuming it is correct, what do you know with certainty about their model?
