To find the mode, or modal value, it is best to put the numbers in order. Then count how many of each number. A number that appears most often is the mode.The Range is the difference between the lowest and highest values. Example: In {4, 6, 9, 3, 7} the lowest value is 3, and the highest is 9. So the range is 9 − 3 = 6 .
