Here are several scatterplots. The calculated correlations are - 0.487, - 0.977, 0.006, and 0.777. Which is which? Match each scatterplot with its calculated correlation.

Solution

Since scatterplot (a) has moderately strong positive correlation, its correlation coefficient should be 0.777.

Since scatterplot (b) has no linear relation between variables, its correlation coefficient should be 0.006.

Since scatterplot (c) has moderately strong negative correlation, its correlation coefficient should be -0.487.

Since scatterplot (d) has very strong negative correlation, its correlation coefficient should be -0.977.
