Measures of variability, as the name suggests, provide information about the degree of variation or dispersion in a dataset. Range is one of the measures of variability, but it is not always the most useful one. Weighted mean, on the other hand, is not a measure of variability but a measure of central tendency. Therefore, only option A is true.
