​How is an Average (Mean) Calculated?

​If you are curious about the mathematics behind the tool, the average we calculate is known as the “Arithmetic Mean”. The formula is simple:

​Average = Sum of all numbers ÷ Total count of numbers

​For example: If your data set is 10, 15, 20, and 25.

  • ​First, find the sum: 10 + 15 + 20 + 25 = 70.
  • ​Next, count the numbers: There are 4 numbers.
  • ​Finally, divide the sum by the count: 70 ÷ 4 = 17.5.

​Our tool performs this exact calculation, even if you paste thousands of numbers at once!
