Merits & Demerits of Median

Merits of Median

• Median is not influenced by extreme values because it is a positional average.
• Median can be calculated in case of distribution with open-end intervals.
• Median can be located even if the data are incomplete.

Demerits of Median

• A slight change in the series may bring drastic change in median value.
• In case of even number of items or continuous series, median is an estimated value other than any value in the series.
• It is not suitable for further mathematical treatment except its use in calculating mean deviation.
• It does not take into account all the observations.
