Consider the following set of 10 test scores:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10
What is the
median of the test scores?
6
5.5
5
4.5
Solution
There is an even number of test scores, so the median will be the mean of the 2 middle numbers.
The two numbers in the middle are 5 and 6. Taking the average of these two numbers give:
$\dfrac{5 + 6}{2} = 5 . 5$
