Which of the following statements is correct? a. The stronger the linear relationship between two variables, the closer the correlation coefficient will be to 1.0. b. Two variables that are uncorrelated with one another may still be related in a nonlinear manner. c. A scatter plot showing two variables with a positive linear relationship will have all points on a straight line. d. All of the above are correct.
No zero-order relationship exists, but a relationship does appear when the two variables are examined in the presence of a control variable. The control variable in this situation is known as a(n) a. ghost variable. b. suppressor variable. c. distorter variable. d. incremental variable. e. magic variable
If all else remains constant and the values of two variables move in the same direction it indicates a Select one: a. the values of the two variables will move in the same direction then move in opposite directions. O b. positive slope relationship. O c. inverse slope relationship. d. negative slope relationship.
Consider a two-dimensional scatterplot representing the relationship between two continuous variables. If the correlation coefficient is -1, then: a. All points lie in a straight line with a slope of -1. b. All points lie in a straight line with an unknown negative slope. c. All points do not lie in a straight line but the best fitting regression line has a slope of -1. d. There is a strong positive relationship between the two variables.

A research analyst states that the correlation between two variables is statistically significant from zero (with r = 0.85). Which of the following conclusion is appropriate? High values of one variable tend to be associated with low values of the other variable. For every unit of change in one variable tend to be associated with .85 values of the other variable. (C) Any association between the two variables does not appear to be linear. (D) 0.85 indicates...
