Getting the average of a collection of figures is reasonably straightforward. Divide the total of those numbers added together by the quantity of digits in that set. An example of such is below.
The number set: 43, 8, 34, 16, 10, 90
The total value of these numbers is = 201
The quantity of numbers is = 6
201 (value) / 6 (quantity) = 33.5
The average number out of that set is 33.5
You can work out the average of a number set yourself quite quickly but if you’re lacking time, an average calculator is even quicker. It can also handle of numbers involving decimal places – a process that might take longer if you were to work it out yourself.
Equally valuable is a weight average calculator. This tool enables you to give weight to numbers to either increase their importance or decrease it. An example where this average is essential is for a grade point average (GPA). Follow this formula below.
1. Multiply the letter grade by the quantity of credits in the class
2. Repeat the process for all of your classes and write down the sum
3. Divide the final figure by how many credits you have
For example:
You received four credits for an A grade, 7 for B grade, and 1 for C grade.
Assign values to the letters of A (4), B (3) and C (2).
Your GPA = [4 (4) + 3 (7) + 2 (1)] / (4 + 7 + 1) = 3.25
