Question

If the coefficient of correlation is positive, then for the values of the variables $x,y$ when the value of $x$ increases perfectly, then

• A. The value of $y$ increases
• B. The value of $y$ decreases
• C. The value of $y$ remains constant
• D. Nothing can be said

Answer 1

The correct option is A

The value of $y$ increases

Explanation for the correct option.

Given that, the correlation coefficient is positive & the value of $x$ increases.

The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.

So, if the value of $x$ increases then the value of $y$ increases.

Hence, option A is correct.
