In one study, it was found that the correlation coefficient between two variables is -0.98. Which statement is true?
Vadim26 [7]

<u>Answer- </u>D. There is a strong negative association between the variables

<u>Solution-</u>

Properties of Correlation Coefficient

1-  Its value ranges between -1 and 1.

2- The greater the absolute value of correlation coefficient, the stronger is the linear relationship.

3- The weakest linear relationship is indicated by a correlation coefficient equal to 0.

4- A positive correlation means that if one variable gets bigger, the other variable tends to get bigger.

5- A negative correlation means that if one variable gets bigger, the other variable tends to get smaller.

As the given correlation coefficient is -0.98 (-ve), whose absolute value is 0.98 (closer to 1)

So there is a strong negative association between the variables.
