What do means mean and median mode?

he mean is the average of the numbers: a calculated "central" value of a set of numbers.It is easy to calculate: Just add up all the numbers, then divide by how many numbers there are.Example: what is the mean of 2, 7 and 9?Add the numbers: 2 + 7 + 9 = 18Divide by how many numbers (i.e. we added 3 numbers): 18 ÷ 3 = 6So the Mean is 6The Median is the "middle number"To find the Median, place the numbers you are given in value order and find the middle numberLook at these numbers:3, 13, 7, 5, 21, 23, 39, 23, 40, 23, 14, 12, 56, 23, 29If we put those numbers in order we have:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56There are fifteen numbers. Our middle number will be the eighth number:3, 5, 7, 12, 13, 14, 21, 23, 23, 23, 23, 29, 39, 40, 56The median value of this set of numbers is 23.
