What is the strongest correlation coefficient?
Understand the Problem
The question is asking about the strongest possible correlation coefficient, which measures the strength and direction of a linear relationship between two variables. The highest possible value for the correlation coefficient is 1, which indicates a perfect positive correlation.
Answer
+1 or -1
The strongest correlation coefficient is the one closest to +1 or -1.
Answer for screen readers
The strongest correlation coefficient is the one closest to +1 or -1.
More Information
A correlation coefficient close to +1 indicates a strong positive relationship, while one close to -1 indicates a strong negative relationship.
Tips
Common mistakes include confusing the sign (positive or negative) with the strength of the correlation. The strength is determined by the absolute value, not the sign.
