Question

the median of 5, 7, 2, 9, 8 is: 1 point 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.
Ascending order: \(2, 5, 7, 8, 9\)

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 \(\frac{5 + 1}{2}=3^{\text{rd}}\) value in the ordered list.
Looking at the ordered list \(2, 5, 7, 8, 9\), the \(3^{\text{rd}}\) value is \(7\).

Answer:

7 (corresponding to the option with "7")
