Question

Suppose we know the correlation between IQ and age in years is 0.12. If we change the units on age to months, the new correlation will be ___________.

Answer 1

0.12

Explanation:

Statistical correlations are obtained by using standardized values of observation. Therefore, unit changes don't interfere in the correlation value.

Based on that reasoning, by changing age units from years to months, the IQ and age correlation remains the same, 0.12.
