The value of Pearson's r for variables A and B is -.80
a. Which is true about cases that have a high value on A: likely to have low value on B, likely t have high value on B, or equally likely to have a low or high value on B?
b. Which is true about the cases that have a low value on A: likely to have a low value on B, likely to have a high value on B, or equally likely to have a low or high value on B?
Homework Answers
A and B are negatively correlated. Hence,
a) High value of A is likely to have low value on B.
b) Low value of A is likely to have a high value on B.

Consider the variables of job satisfaction and perceived job security. It seems logical that these go hand in hand; it would make sense for them to be connected in some way. Suppose that a study was conducted on these variable, and the correlation coefficient was found to be .61 (r = .61). Develop a main response in which you address the following: Explain what a Pearson's r value of .61 would imply about the relationship for these variables (strength and...
