    measures of dispersion the different ways of calculating the extent to which a set of observations, numbers, etc., are clustered together round a central point. Measures of dispersion are closely related to MEASURES OF CENTRAL TENDENCY. There are six measures: the range, variance, standard deviation, standard error, skew, and kurtosis.

    These quantities measures the dispersion in the same units as the units of original data. Absolute measures cannot be used to compare the variation of two or more series/ data set. A measure of absolute dispersion does not in itself, tell whether the variation is large or small.

  • Measures of Dispersion

     · Measures of dispersion describe the spread of data around a central value (mean, median or mode). They tell us how much variability there is in the data. There are two measures of dispersion: range (where you subtract the lowest score from the highest score) and standard deviation (SD) - which calculates the spread of scores around the mean.
