What is the median of these numbers: 11, 13, 4, 9

10

Step-by-step explanation:

11, 13, 4, 9

In order to find the median we must first arrange the numbers in order (Least to greatest)

4, 9, 11, 13

If there is 2 numbers in the middle: the median is their average

If there is only one number in the middle, that number is the median.

Since there are two numbers (9 and 11) we have to take their average.

(9+11) / 2 = 20 / 2 = 10

The median is 10!

The median for the numbers: 11, 13, 4, 9 is 29
