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. |
Homework Answers
Ans:
Option b is correct.
All points lie in a straight line with an unknown negative slope.
(as slope=r*sy/sx=-sy/sx)

Determine whether each of the following statements regarding the correlation coefficient is true or false. The correlation coefficient equals the proportion of times that two variables lie on a straight line. The correlation coefficient will be +1.0 if all the data points lie on a perfectly horizontal straight line. The correlation coefficient measures the strength of any relationship that may be present between two variables. The correlation coefficient must always lie between –1.0 and +1.0.

is consider a situation where two variables appear to have nearly a linear relationship, meaning that the points in a scatter plot roughly follow a straight-line pattern. If the dependent, or response, variable increases as the independent, or explanatory, variable increases, then the linear pattern would have a: (A) Negative slope (B) Positive slope (C) Zero slope (D) An undefined slope 19. The value of r, the correlation coefficient for a sample, always takes on values between: (A) 0 and...
