Statistics, multiple choice, correlation coefficient

AI Thread Summary
Set A has a correlation coefficient of -0.75, indicating a strong negative relationship, while Set B has a coefficient of +0.55, indicating a moderate positive relationship. The strength of a correlation is determined by the absolute value of the coefficient, meaning that -0.75 is indeed stronger than +0.55. Therefore, Set A exhibits a stronger strength of relationship compared to Set B. Understanding correlation coefficients is crucial for analyzing the strength and direction of relationships between data sets.

Homework Statement


The correlation coefficient for each of two data sets is calculated. Set A has r = -0.75 while Set B has r = +0.55. Which set (A or B) has the stronger strength of relationship?


Homework Equations

I think -0.75?



The Attempt at a Solution



I think Set A r = -.75 is stronger because it is closer to -1
