Question

which correlation coefficient represents the strongest downward trend in a data set?
a. -0.83
b. -0.23
c. 0.12
d. 0.92

Explanation:

Step1: Recall correlation basics

Correlation coefficients range from -1 to 1. Negative values mean downward trends; absolute value indicates strength.

Step2: Compare absolute values

Options A (-0.83), B (-0.23) are negative. |-0.83| > |-0.23|, so A is stronger.

Answer:

A. -0.83
