**Merits of Median:**

- It is easy to understand and calculate
- It is not affected by extreme values. As an example, consider the following data sets and their central tendencies. As an example, consider the following data sets and their central tendencies.

**In the above table, the value 500 creates a huge difference in the mean but brings no change in the mode and median.**

- It can be located graphically
- Median can be calculated for open end class intervals and for unequal class intervals
- It is the best measure for qualitative data such as beauty, intelligence, honesty

**Demerits of Median:**

- It is based on the middle observation only and doesn’t provide a picture of the entire data.
- It cannot be used for further mathematical treatment
- It does not have sampling stability so sampling fluctuations can be high.
- It is not based on all observations
- It cannot represent the irregularly distributed data
