Match each situation with its level and sign of correlation. A correlation with an absolute value larger than 0.7 is considered strong.
Weak Positive Correlation
Strong Positive Correlation
Weak Negative Correlation
Strong Negative Correlation
Select all the values for r that indicate a positive slope for the line of best fit.
The correlation coefficient, r, is given for several different linear models for a data set. Sort the r values from best fit (top) to worst fit (bottom).
-0.95
-0.82
-0.34
0.01
