1. Finding Average 

Finding the average

Finding the average is a very straightforward concept.If you have a set of numbers, the average is found by adding all numbers in the set and dividing their sum by the total number of numbers added in the set.


Let us illustrate with examples:

Example #1:

Get the average of the following set of numbers:

5,4,12,2,1,6

Step 1:

Find the sum:

Sum = 5+4+12+2+1+6= 30

Step 2:

Divide 30 by 6 (the total number of numbers)

30 divided by 6 is 5, so the average is 5

Example #2:

Get the average of the following set of numbers:

5,10,20,5,,10

Find the sum:

Sum = 5+10+20+5+10=50

Divide the 50 by 5 (the total number of numbers added)

50 divided by 5 is 10, so 10 is the average.
