If you created a correlational model on a data set, and the numeric value indicating the strength of the relationship between two attributes was calculated to be 0.38, you would conclude that there is __________ correlation between the two attributes.

• A. Strong
• B. Moderate
• C. No
• D. Negative

Answer: (C)

A correlation coefficient of 0.38 shows a moderate positive linear relationship between the two attributes. The sign is positive, meaning as one attribute tends to rise, the other tends to rise as well. The magnitude indicates strength: values near 0 indicate little to no linear relationship, while values around 0.3 to 0.5 are typically described as moderate. So 0.38 is best described as a moderate positive correlation, not no correlation and not negative.
