According to the data set with median 18.5 It is impossible to determine the missing value.
Median:
- Median is centre number of a ascending or descending list of numbers.
Firstly, let's arrange the numbers in ascending list.
Therefore,
15, 17, 13, 19, 20, 33, 22, 12, 18, and x
<h3 /><h3>Sorted number:</h3>
- 12, 13, 15, 17, 18, 19, 20, 22, 33 and x.
The amount of number is an even number. Therefore, the middle number is two. This means we add them and divide by 2.
Now, we don't know the value of the last number. But we were given the median as 18.5. Therefore, let's test it
18.5 = 18 + 19 / 2
37 / 2 = 18.5
It is impossible to determine the missing value.
