Finding the average or mean of a group of numbers is straightforward. Here is a group of numbers: 15, 31, 39, 50, 32, 42. What is the average of this collection of numbers? The first step is to count the number of values. There are six numbers, so six will be the number on the bottom of a division problem. Now, to add the values together.
15+31+39+50+33+42 = 210
So, following the division formula, students should realize that 210 represents the total of all the numbers added (the top value of the formula). Inserting the numbers:
210/6 = 35
The average value of these six numbers is 35.
