Mean Formula

The arithmetic mean (or average) is calculated by summing all numbers in a dataset and dividing by the count of numbers.

Formula:
Mean = (Sum of all numbers) / (Count of numbers)
Steps

How to Calculate Mean

To calculate the mean, follow these steps:

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

For example, to find the mean of 2, 4, 6, 8, 10:

Example Calculation:
Mean = (2 + 4 + 6 + 8 + 10) / 5 = 30 / 5 = 6
Examples

Mean - Practical Examples

Example 1 Test Scores

A student's test scores are: 85, 90, 88, 92, 87. What is the mean score?

Mean = (85 + 90 + 88 + 92 + 87) / 5 = 442 / 5 = 88.4

Example 2 Daily Temperatures

The daily temperatures for a week are: 72°F, 75°F, 70°F, 68°F, 73°F, 71°F, 74°F. What is the mean temperature?

Mean = (72 + 75 + 70 + 68 + 73 + 71 + 74) / 7 = 503 / 7 = 71.86°F

Example 3 Monthly Expenses

Monthly expenses for a year: $1200, $1300, $1250, $1400, $1350, $1300, $1250, $1200, $1300, $1350, $1400, $1300. What is the mean monthly expense?

Mean = (1200 + 1300 + 1250 + 1400 + 1350 + 1300 + 1250 + 1200 + 1300 + 1350 + 1400 + 1300) / 12 = $1308.33
