Some measures of dispersion depend upon the spread values, whereas some calculate the variation of the values from a central value. Do you agree ?
Yes, it is true that some measures of dispersion depend upon the spread values, whereas some i calculate the variation-of the values from a central j value. Range and quantile deviation measure j the dispersion by calculating the spread within ; which the value he. Mean deviation and standard deviation calculate the extent to which the values differ from the average or the central value.
