Question Which statement about reexpressing data is not true

Question: Which statement about re-expressing data is not true?

A. Unimodal distributions that are skewed to the left can be made more symmetric by taking the square root of the variable.

B. A curve that is descending as the explanatory variable increases may be straightened by taking a logarithm of the response variable.

C. One goal of re-expression may be to make the variability of the response variable more uniform.

Solution

The statement about re-expressing data is not true is:

A. Unimodal distributions that are skewed to the left can be made more symmetric by taking the square root of the variable.
