Find the median if this set of numbers: 7, 6, 19, 12, 16, 19, 19, 6

Answer:

Step-by-step explanation:

Order the numbers from smallest to largest, then cross one number off until you have one or two numbers left.

If there is an EVEN number of numbers(like this one): there will be two numbers left, therefore you add those two numbers together, then divide by two.

If there is an ODD number of numbers: there will be one number left, therefore that is your answer!

Hope this helps!
