While the mean and standard deviation are dimensional quantities (this is why we will take the square root of the variance ) that is, have the same units as the measured quantities xi, the skewness is conventionally defined in such a way as to make it nondimensional.

Recall also that by taking the expected value of various transformations of the variable, we can measure other interesting characteristics of the distribution. In this section, we will study expected values that measure the spread of the distribution about the mean.

Left-skewed distributions show the mean lower than the median, which is lower than the mode, while right-skewed distributions have the mode lower than the median and median lower than the mean. Skewness quantifies a distribution's asymmetry and points to the tail's direction, with negative values indicating left skew and positive values indicating right skew.
