18. The Pearson correlation measures a. the degree of relationship without regard to the form of the relationship. c. the degree to which the relationship is consistently one directional. d. the degree of linear relationship. e. the degree of curvilinear relationship. 19. If there is a negative correlation between X and Y, then the regression equation Y = bX + a will have a. b > 0 b. b < 0 c. a > 0 d. a < 0 20. In the general linear equation, Y = bX + a, the value of b is called a. the X-intercept b. the Y-intercept c. correlation between X and Y d. slope 21. The chi-square test for goodness-of-fit evaluates a. the relationship between two variables.. b. the mean differences between two or more treatments. c. the shape or proportion for a population distribution. d. none of the above. 22. A basic assumption for chi-square hypothesis test is a. the population distribution(s) must be normal. c. the scores must come from an interval or ratio scale. a. the observations must be independent. b. all of the above.

The strength of the relationship between two quantitative variables can be measured by Multiple Choice both the coefficient of correlation and the coefficient of determination. the y-intercept of the simple linear regression equation. the coefficient of correlation. the slope of a simple linear regression equation. the coefficient of determination.
