The log transformation is used to reduce skewness of a measurement variable. If the distribution becomes symmetric, the Welch t-test can be used to compare groups. If the distribution becomes close to normal, a reference interval can be determined.
The log transformation is often used to reduce skewness of a measurement variable. If, after transformation, the distribution is symmetric, then the Welch t-test might be used to compare groups. If, also, the distribution becomes close to normal, then a reference interval might be determined.
