Answer #1

r = 1.00 Perfect (positive) correlation

Explanation: The correlation values lies between -1 to +1, where -1 means, the two variables are perfectly (positive) correlated and +1 means, the two variables are perfectly (negative) correlated.

r = -0.95 Strong (negative) correlation

Explanation: The values lies between -0.80 to -1.00 means the two variables are strongly (negative) correlated.

r = 0.30 Weak (positive) correlation.

Explanation: The values lies between 0.2 to 0.50 means the two variables are weakly (positive) correlated.
