Overview & Explanation

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

How It Works

  • Sum all numbers in the dataset.
  • Count total numbers in the list.
  • Divide sum by count.

Practical Applications

  • Calculating test grade averages.
  • Determining average monthly expenses.

Worked Example: Average of 10, 20, 30, 40, 50

Find the mean.

1

Sum of Values

10 + 20 + 30 + 40 + 50

= 150
2

Divide by Count (5)

150 / 5

= 30
