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 sort the 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 for \(n = 5\) numbers is at \(\frac{n + 1}{2}=\frac{5+ 1}{2}=3\)rd position. Looking at the sorted list \(2, 5, 7, 8, 9\), the 3rd number is \(7\).

Answer:

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