D
r = - .65
Verified step by step guidance1
Understand that the strength of a correlation is determined by the absolute value of the correlation coefficient, regardless of its sign.
Recall that correlation coefficients range from -1 to +1, where values closer to -1 or +1 indicate a stronger relationship.
Compare the absolute values of the given correlation coefficients: |+0.25|, |+0.55|, |-0.10|, and |-0.65|.
Identify which of these absolute values is the largest, as this will indicate the strongest relationship.
Conclude that the correlation coefficient with the largest absolute value represents the strongest relationship between the two variables.
