WitrynaLogarithms (frequently referred to as ‘logs’) are often used in statistics. Medical statisticians log-transform skewed data to make the distribution of the data more … The logarithm transformation and square root transformation are commonly used for positive data, and the multiplicative inverse transformation (reciprocal transformation) can be used for non-zero data. The power transformation is a family of transformations parameterized by a non-negative value λ that includes the logarithm, square root, and multiplicative inverse transformations as special cases. To approach data transformation systematically, it is possible to use statistical est…

One nice property of the CV is that it does not change if you scale all the data by a constant factor. The SD of the log-transformed data shares this property. Your proposed measure (SD/mean of the log-transformed data) does not share this property. Lewontin (1966) may help elucidate some of these issues.
