Question 4 • CMS 2026-2027 NC Math 1 CREDIT RECOVERY

Which r -value represents the strongest correlation?

Answer
A
0 point 4 8
B
0 point 7 9
C
negative 0 point 8 3
D
negative 0 point 6 7

Explanation

The strength of a correlation depends on the absolute value of r: the closer |r| is to 1, the stronger the correlation. The absolute values are 0.79, 0.48, 0.83, and 0.67. The largest is 0.83, so r = −0.83 represents the strongest correlation; the negative sign indicates its direction, not its strength.
