Question

which of these r values represents the strongest correlation?
a. -0.7
b. -0.4
c. -0.5
d. -0.6

Explanation:

Correlation strength is determined by the absolute value of the correlation coefficient $r$, where values closer to 1 or -1 indicate a stronger correlation. Calculate the absolute value of each option:

• $|-0.7| = 0.7$
• $|-0.4| = 0.4$
• $|-0.5| = 0.5$
• $|-0.6| = 0.6$

0.7 is the largest absolute value, so -0.7 represents the strongest correlation.

Answer:

A. -0.7
