# Relation between the standard deviation of logarithmized sample and the non-logarithmized sample values

## Description

Log-normal (or lognormal) distribution is a continuous probability distribution of a random variable whose logarithm is normally distributed. The standard deviation measures the amount of variation or dispersion from the average.
