Question

If $r=0.2$, then the linear correlation will be necessarily

• A. Perfect
• B. Negative
• C. Very low
• D. Very high

Answer 1

The correct option is C

Very low

Explanation for the correct option.

The correlation coefficient, $r$, is used to measure the extent of the statistical relationship between two interval or ratio level variables.

Higher the value of $r$ stronger the correlation.

Here, $r=0.2$ which is less therefore, this is a very low correlation.

Hence, option C is correct.
