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. So 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 set. Looking at the ordered set \(2, 5, 7, 8, 9\), the 3rd value is \(7\).

Answer:

B. 7 (assuming the options are labeled as A. 5, B. 7, C. 8, D. 6)
