Question

which value of a correlation coefficient represents the strongest relationship between the two variables in a given linear regression model?

○ 0.91

○ -0.94

○ 0.5

○ 0

Explanation:

The strength of a linear relationship from a correlation coefficient is determined by its absolute value, where values closer to 1 or -1 indicate a stronger relationship. Calculate the absolute values of each option:

• $|0.91| = 0.91$
• $|-0.94| = 0.94$
• $|0.5| = 0.5$
• $|0| = 0$

0.94 is the largest absolute value, so -0.94 represents the strongest relationship.

Answer:

B. -0.94
