For each of the following summaries, first indicate what the usual interpretation would be, then indicate whether there are any other possibilities.
a. r = 1.
b. r = 0.85.
c. r = 0.
d. r= -0.15.
e. r = -1.
First, the correlation coefficient, denoted by r, is a measure of the strength of the straight-line or linear relationship between two variables.
Then for the question,
a. r = 1. +1 indicates a perfect positive linear relationship: as one ...
This solution shows how to interpret various statistics summaries and indicates whether or not they could be interpreted in another way.
