Question

the median of 5, 7, 2, 9, 8 is:
5
7
8
6

Explanation:

Step1: Order the numbers

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 set with \(n\) numbers (where \(n\) is odd) is the middle number. Here, \(n = 5\) (odd), so the middle number is the \(\frac{5 + 1}{2}= 3\)-rd number in the ordered list.
The 3rd number in \(2, 5, 7, 8, 9\) is \(7\).
