Question

1. describe each of the following correlation coefficients using the terms strong, moderate, or weak and negative or positive. a. r = -0.99 b. r = 0.57 c. r = 0.09999

Explanation:

The correlation coefficient (r) ranges from - 1 to 1. A value close to -1 indicates a strong negative correlation, a value close to 1 indicates a strong positive correlation, a value around 0 indicates a weak correlation.

• For a. r = - 0.99, since it is close to -1, it is a strong negative correlation.
• For b. r = 0.57, it is between 0.3 and 0.7, so it is a moderate positive correlation.
• For c. r = 0.09999, it is close to 0, so it is a weak positive correlation.

Answer:

a. Strong negative correlation
b. Moderate positive correlation
c. Weak positive correlation
