Question

find the median of this data set: 4, 7, 3, 5, 6

Explanation:

Step1: Sort the data set

Sort the numbers in ascending order: $3,4,5,6,7$

Step2: Find the median

Since there are $n = 5$ (odd number) of data points, the median is the $\frac{n + 1}{2}$-th value.
$\frac{5+ 1}{2}=3$ -rd value.
The 3 -rd value in the sorted set $3,4,5,6,7$ is $5$.

Answer:

$5$
