find the median of this data set. 85, 40, 68, 37, 90, 66, 60, 72

Explanation:

Step1: Arrange data in ascending order

$37,40,60,66,68,72,85,90$

Step2: Determine number of data points

There are $n = 8$ data - points. Since $n$ is even, the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+1)$th ordered data points. $\frac{n}{2}=\frac{8}{2}=4$ and $\frac{n}{2}+1 = 5$

Step3: Calculate the median

Median=$\frac{66 + 68}{2}=\frac{134}{2}=67$

Answer:

$67$
