The linear correlation coefficient is a numerical value that ranges from -1.00 to +1.00. Describe in a sentence or two the meaning of each of these correlation coefficients:

a) -1.00 b) +1.00

a) Perfect predictability, where one variable increases, while the other decreases.

b) Perfect predictability, where both variable increase/decrease together.

Oh....I understand a little better now...thank you!

a) A linear correlation coefficient of -1.00 indicates a perfect negative correlation between two variables, meaning that as one variable increases, the other variable decreases in a perfectly predictable way.

b) A linear correlation coefficient of +1.00 indicates a perfect positive correlation between two variables, meaning that as one variable increases, the other variable also increases in a perfectly predictable way.
