Question

what is the median?
4 3 9 3 1 1 8 1 4

Explanation:

Step1: Sort the data

First, we sort the given numbers: \(1, 1, 1, 3, 3, 4, 4, 8, 9\)

Step2: Find the median

The median is the middle value of a sorted data set. Since there are 9 numbers (an odd number of observations), the median is the \(\frac{9 + 1}{2}=5\)-th value in the sorted list.
Looking at the sorted list \(1, 1, 1, 3, 3, 4, 4, 8, 9\), the 5th value is \(3\).

Answer:

\(3\)
