Categories (also known as nominal or categorical variables) cannot have a meaningful low-to-high range of values that can be averaged to have a no-nonsense mean and standard deviation. Continuous variables (also known as interval- or ratio-level variables) can easily be placed on a continuum with a mean and standard deviation.
