Merits or Uses of Median:

1. Median is rigidly defined as in the case of Mean.

2. Even if the value of extreme item is much different from other values, it is not much affected by these values e.g. Median in case of 4, 7, 12, 18, 19 is 12 and if we add two values equal to 450 10000, new median is 18.

3. It can also be used for the Quantities; those can’t give A.M; as is in case of intelligence etc. It is possible to arrange in any order and to locate the middle valve. For such cases it is the best measure.

4. It can be located graphically.

5. For open end intervals, it is also suitable one. As taking any value of the intervals, value of Median remains the same.

6. It can be easily calculated and is also easy to understand

7. Median is also used for other statistical devices such as Mean Deviation and skewness.

8. It can be located by inspection in some cases.

9. Extreme items may not be available to get Median. Only if number of terms is known, we can get median e.g.

Find median of the 9 terms, out of which first two and last three terms are missing and middle four terms are 7, 9, 10, 14. Here we can calculate as following let nine terms be

Here out of nine terms middle term is; (n+1/2) Thus 10 is the Median.
