What does a high correlation coefficient indicate about two variables?

• A. They are independent
• B. They have no relationship
• C. They have a strong relationship
• D. They are irrelevant to each other

Answer: (C)

A high correlation coefficient indicates that there is a strong relationship between two variables. Correlation coefficients range from -1 to 1, where values closer to 1 imply a strong positive relationship (as one variable increases, the other tends to increase as well), and values closer to -1 imply a strong negative relationship (as one variable increases, the other tends to decrease). When the correlation coefficient is high, it suggests that changes in one variable are closely associated with changes in the other, reflecting a predictable pattern of behavior between the two. This relationship can be essential for understanding the dynamics and interactions between variables in research and practice, making it a key concept in data analysis for fields such as counseling and psychology.
