Question

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

5

7

8

6

Explanation:

Step1: Arrange the numbers in order

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

Step2: Find the middle number

Since there are 5 numbers (an odd number of observations), the median is the middle number. The middle position in a set of \(n\) numbers (where \(n\) is odd) is at \(\frac{n + 1}{2}\)th position. Here \(n = 5\), so \(\frac{5+ 1}{2}=3\)rd position. Looking at the ordered set \(2, 5, 7, 8, 9\), the 3rd number is \(7\).

Answer:

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