How to calculate the average?

To calculate the average (also known as the mean) of a set of numbers, follow these steps:

  1. Add up all the numbers in the set.
  2. Count how many numbers there are in the set.
  3. Divide the sum by the count.

Here's the formula:

Average = (Sum of all numbers) / (Count of numbers)

For example, let's say you have the following set of numbers: 4, 7, 2, 9, 5.

  1. Add up all the numbers in the set: 4 + 7 + 2 + 9 + 5 = 27
  2. Count how many numbers there are in the set: There are 5 numbers in the set.
  3. Divide the sum by the count: 27 / 5 = 5.4

Therefore, the average (or mean) of this set of numbers is 5.4.
