Answer 1

1) It is easy to compute and understand.

2) It is well defined an ideal average should be.

3) It can also be computed in case of frequency distribution with open ended classes.

4) It is not affected by extreme values and also interdependent of range or dispersion of the data. 

5) It can be determined graphically.

6) It is proper average for qualitative data where items are not measured but are scored.

7)It is only suitable average when the data are qualitative & it is possible to rank various items according to qualitative characteristics.

8) It can be calculated easily by watching the data.
9) In some cases median gives better result than mean.

Answer 2

Median is the middle value of the distribution i.e median of a distribution is the value of the variable which divides it into two equal parts. It is the value of the variable such that the number of observations above it is equal to the number of observations below it.

MERITS:

Merits of Median:

1. It is simple to understand and easy to calculate, particularly is individual and discrete series.

2. It is not affected by the extreme items in the series.

3. It can be determined graphically.

4. For open-ended classes, median can be calculated.

5. It can be located by inspection, after arranging the data in order of magnitude.
