Mean, Median, Mode and Range

Mean, Median, Mode and Range

(Mean, median, and mode are three kinds of "averages".)

1Mean is found by adding the numbers and dividing the sum by the number of numbers in the list.

                                                                                                                                                                                                                                         

2Median is the "middle" value in the list of numbers ordered from smallest to largest.

                                                                                                                                                                                                                                         

3Mode is the value that occurs most often. If no number in the list is repeated, then there is no mode for the list.

                                                                                                                                                                                                                                         

4Range is the difference between the largest and smallest values of a list of numbers. It expresses "spread" (or how distributed or concentrated the values are).
