The r value ranges from 0 to 1, where 0 means no relationship, and 1 means 100% related.

Which is an error and the range of r value is between 1 and 1.

Correlation coefficients are always values between -1 and 1, where -1 shows a perfect, linear negative correlation, and 1 shows a perfect, linear positive correlation. The list below shows what different correlation coefficient values indicate:

Exactly –1. A perfect negative (downward sloping) linear relationship

–0.70. A strong negative (downward sloping) linear relationship

–0.50. A moderate negative (downhill sloping) relationship

–0.30. A weak negative (downhill sloping) linear relationship

0. No linear relationship

+0.30. A weak positive (upward sloping) linear relationship

+0.50. A moderate positive (upward sloping) linear relationship

+0.70. A strong positive (upward sloping) linear relationship

Exactly +1. A perfect positive (upward sloping) linear relationship
