✓

Answer

  • Mean deviation is most widely used measure of dispersion is based on all the values of a series, whereas Quartile Deviation is not based on all the observations, so it is less reliable than the mean deviation.
  • Mean deviation is not suitable for open-ended classes (as it can not be calculated), whereas Quartile Deviation is the only measure of dispersion which can be used to deal with an open-ended distribution.
