What is the median of the following set of numbers?

1 answer:

7 0

To find the median, we must order the numbers.

12,12,13,13,14,15,16,17,18,19

Now see which one is in the middle.

We are stuck between 14 and 15, so what is between those?
14.5 is between 14 and 15, so that is the median.

Answer: 14.5 is the median
