Question

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

Explanation:

Step1: Arrange numbers in order

Arrange the data set \(5, 7, 2, 9, 8\) in ascending order: \(2, 5, 7, 8, 9\).

Step2: Find the middle value

For a data set with \(n = 5\) (odd number of observations), the median is the middle value, which is the \(\frac{n + 1}{2}\)-th value. Here, \(\frac{5+1}{2}=3\)-rd value. Looking at the ordered set \(2, 5, 7, 8, 9\), the 3rd value is \(7\).

Answer:

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