Suppose that a relationship between presidential voting preference and gender has a statistical significance level of .001 and the P-R-E measure of association for this relationship is .35. Which of the following statements is correct? (Answer: B)
A. By knowing the dependent variable gender, we can reduce the number of errors in predicting the independent variable presidential voting preference by 35.

C. The relationship is not statistically significant; accept the null hypothesis.
D. There is a statistically significant relationship, but the relationship is not strong enough to be of any theoretical importance.
Which of the following does a P-R-E measure of association tell us?
A. the degree of relationship between the dependent variable and the independent variable
