Description: Here we give you a set of numbers and then ask you to find the mean, median, and mode. It's your first opportunity to practice with us! Created by Sal Khan and Monterey Institute for Technology and Education. Find the mean, median, and mode of the following sets of numbers. Sometimes it's called the arithmetic mean because you'll learn that there's other ways of actually calculating a mean. We want to average 23 plus 29 or we're going to sum 23 plus 29 plus 20 plus 32 plus 23 plus 21 plus 33 plus 25, and then divide that by the number of numbers.
