Find the median

Answer 1

Average value is

For Median lets go as below:

The first step is to sort values.

The sorted values are 2,3,4,6,7,8,8,8,8

Next, the median value depends on the number of values. If the number of values is odd, then the median is the "central" value among the sorted values. If the number of values is even, then the median is the average of the two "central values".

We have 9 values, so their number is odd.

Since the number is odd, the median is the "central value": 7

Hence median is 7
