The mean is where you add all the numbers there in front of you and then after you have done that you will divide how many number you see or just count and divide with the number you added together i mean the answer and you will get your answer.
You put the number from greater to least and find the middle number but if there are 2 middle numbers add them together and divide them by 2 and there your answer.
Super easy just find the number that are being repeated.
