When arranged in ascending or descending order, the median is the value which lies half-way along the series.
Where there is an even number of values in the set then the median is the mean of the middle two values.
As there are 7 values in the given set, and one is missing, then the full set comprises 8 values.
2,7,8,14,15,20,29.
The middle value is 14 so we need another value, v such that, ½(14 + v) = 13.
This solves as v = 12.
The full set now is,2,7,8,12,14,15,20,29.

It is 13, the number halfway between the two middle numbers.
The median is simply the number in the middle when ordered from least to greatest. Since there is an even number of terms here, simply find the average of the middle two. In this case, the average of 8 and 11 is 9.5 Therefore, the median is 9.5

Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
13
the median is the number in the middle. If there are two number sin the middle ( when total sample is even) take the average of the two(14 + 18)/2 = 16
14, which is the middle number when they are listed in order.
The median is 15.

The median is 30, the middle number when they are in order.
It is 15.
