Question

the median of 5, 7, 2, 9, 8 is:

5

7

8

6

Explanation:

Step1: Order the data set

First, we need to arrange the numbers \(5, 7, 2, 9, 8\) in ascending order. When we sort them, we get \(2, 5, 7, 8, 9\).

Step2: Find the median

The median of a data set with \(n\) values (where \(n\) is odd) is the middle value. Here, \(n = 5\) (which is odd), so the middle value is the \(\frac{5 + 1}{2}=3\)-rd value in the ordered list. The ordered list is \(2, 5, 7, 8, 9\), and the 3rd value is \(7\).

Answer:

7 (corresponding to the option "7")
