Question

the median of 5, 7, 2, 9, 8 is: 1 point 5 7 8 6

Explanation:

Step1: Arrange the numbers in order

First, we 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 \(n = 5\) numbers (an odd number of observations), the median is the middle number. The middle number is the \(\frac{n + 1}{2}\)-th term. For \(n=5\), \(\frac{5+ 1}{2}=\frac{6}{2}=3\)-rd term. Looking at the ordered list \(2, 5, 7, 8, 9\), the 3rd term is \(7\).

Answer:

7 (corresponding to the option with "7")
