Study results excerpt ...men's romantic popularity significantly correlated with several characteristics, such as best dressed (r=0.51), most physically attractive (r = 0.46), most outgoing (r = 0.46), most self-confident (r = 0.44), best trendsetters (r = 0.39), funniest (r = 0.36), most satisfied (r = 0.34), and most independent (r = 0.28). Unexpectedly, however, men's potential for financial success did not significantly correlate with romantic popularity (r = 0.11). Print DoneTwo researchers collected ratings and nominations on a number of characteristics for 66 fraternity men from their fellow members. The accompanying paragraph is taken from their results section. Complete parts (a) through (c) below. Click the icon to view the study results excerpt. (a) Explain what is meant by a correlation coefficient, using one of the correlations as an example, as if writing to a person who has never had a course in statistics. Choose the correct answer below. O A. A correlation coefficient tells the strength and direction of a linear relationship. The correlation coefficient between romantic popularity and best dressed of 0.51 shows a fairly strong positive relationship; better-dressed men tended to be more romantically popular. O B. A correlation coefficient tells about percentage change in one variable given a second variable. The correlation coefficient between romantic popularity and best dressed of 0.51 shows the most romantically popular men were 51% better dressed. O C. A correlation coefficient tells about percentage change in one variable given a second variable. The correlation coefficient between romantic popularity and best dressed of 0.51 shows the best dressed men were 51% more romantically popular. (b) Explain in a general way what is meant by "significantly" and "not significantly", referring to at least one specific example, as if writing to a person who has never had a course in statistics. Choose the correct answer below.. . . (b) Explain in a general way what is meant by "significantly" and "not significantly", referring to at least one specific example, as if writing to a person who has never had a course in statistics. Choose the correct answer below. O A. "Significantly" correlated variables tend to vary proportionally with each other, while variables that are "not significantly" correlated do not. As romantic popularity goes up at a certain rate, physical attractiveness tends to follow it strongly, but potential for financial success does not follow romantic popularity very strongly at all. O B. "Significantly" correlated variables are the most important variables in a study, while variables that are "not significantly" correlated are less important. The two researchers are more concerned with men that dress well than man with the potential to be wealthy. O C. "Significantly" correlated variables are more logically connected than variables that are "not significantly" correlated. It makes more logical sense for a self-confident man to be romantically popular than a man with the potential to be wealthy. (c) Speculate on the meaning of the pattern of results as if writing to a person who has never had a course in statistics, taking into account the issue of direction of causality.

(c) Speculate on the meaning of the pattern of results as if writing to a person who has never had a course in statistics, taking into account the issue of direction of causality. Choose the correct answer below. O A. In this fraternity, being better-dressed tends to make a man romantically popular more consistently than being outgoing, which itself tends to make a man romantically popular more consistently than being funny. O B. In this fraternity, being better-dressed makes a man more romantically popular than being outgoing, which itself makes a man more romantically popular than being funny. O C. In this fraternity, being romantically popular is likely to make a man better-dressed, more outgoing, and funnier, though the chances of becoming better-dressed are greater than the chances of becoming more outgoing, which are greater than the chances of becoming funnier
