question 18
find the median value of the following 5 test scores:70, 95, 85, 70, 60
a 70
b 85
c 76
d 75

Explanation:

Step1: Sort the data

Sort the test scores in ascending order: $60,70,70,85,95$.

Step2: Find the median

For a set of $n = 5$ (odd number) data points, the median is the $\frac{n + 1}{2}$-th value.
Here, $\frac{5+ 1}{2}=3$-rd value.
The 3 - rd value in the sorted list $60,70,70,85,95$ is $70$.

Answer:

A. 70
