Mode is the most occuring number in a set.Median is the middlemost number in a set if the numbers were arranged in ascending order from left to right.Mean is the average of all the numbers in the set, so you'd add all the numbers together and divide by the total number of elements in the set.Example:{4, 2, 6, 5, 3, 2, 2, 8}Here is a set of numbers. Find the mean, median, and mode.Mean: Add all the numbers together, then divide by the total number of numbers in the set.4 + 2 + 6 + 5 + 3 + 2 + 2 + 8 = 3232 / 8 = 4.The mean is 4.Median: To find the median, you must first order the set of numbers into ascending order.{2, 2, 2, 3, 4, 5, 6, 8}If there are two numbers in the middle, then find the average between those two. The two middle numbers are 3 and 4, so the median would be 3 + 4 divided by 2, or 3.5.Mode: This is an easy one. Just find the number that appears the most, list others if they occur the same number of times. The mode is 2.
