Which value of r shows stronger correlation?

Question

When comparing correlation results, which value of r indicates a stronger correlation? I’d like to better understand how to interpret the correlation coefficient.

Jonny · Answer

The value of r closest to +1 or −1 shows the strongest correlation.

For example, r = −0.90 indicates a stronger correlation than r = +0.60, because |−0.90| = 0.90 is greater than |+0.60| = 0.60. Values near 0 indicate weaker linear correlation.

Henna · Answer

The r-value (correlation coefficient) closest to +1 or −1 shows the stronger correlation. For example, r = −0.90 is stronger than r = +0.60 because its absolute value, 0.90, is larger. An r-value near 0 indicates weak or no linear correlation.
