Following are the four flaws of median.
1. The median does not represent the average of a group, in which there is considerable difference in the values of different items.
2. It is not capable of algebraic treatment.
For example, median cannot be used for determining the combined median of two or more groups, as is possible in case of mean.
3. When the median is somewhere between two values, then this is only possible value, not real.
4. To find the median, it is necessary to arrange the data class in ascending or descending order. This work takes time.
