Calculating the Mean (Average) | A Step-by-Step Guide for Math Enthusiasts

What is the mean?

The mean refers to the average of a set of numbers

The mean refers to the average of a set of numbers. It is calculated by adding up all the numbers in the set and then dividing the sum by the total count of numbers in the set.

To find the mean, follow these steps:

1. Add up all the numbers in the set.
2. Count the total number of values in the set.
3. Divide the sum by the total count of numbers.

For example, let’s say we have the set of numbers: 5, 7, 9, 12, 3.

Step 1: Sum = 5 + 7 + 9 + 12 + 3 = 36.
Step 2: Count = 5 (as there are 5 numbers in the set).
Step 3: Mean = Sum / Count = 36 / 5 = 7.2.

Therefore, the mean (average) of the set of numbers is 7.2.
