  • Range is the simplest measure of dispersion.
  • Range uses only the maximum and minimum values of the data.
  • It gives a rough idea of variability.

3. Mean Deviation

  • Mean deviation is the mean of absolute deviations from a chosen central value.
  • It can be found about mean or about median.
  • Absolute values are used so that positive and negative deviations do not cancel.

4. Mean Deviation for Grouped Data

  • Grouped data may be discrete frequency distribution or continuous frequency distribution.
  • Discrete frequency distribution has distinct values with frequencies.
  • Continuous frequency distribution has class intervals without gaps with frequencies.
