Variability refers to the amount of dispersion or spread in a distribution of data for a variable. This can be measured using statistical measures such as standard deviation or variance. Skewness refers to the asymmetry of the distribution, symmetry refers to the balance of the distribution, and modality refers to the number of peaks in the distribution. While these concepts are related, they are not the same as variability.
