About Arithmetic Mean

The arithmetic mean (average) is the sum of a collection of numbers divided by the count of numbers in the collection.

Formula:

\[\bar{x} = \frac{x_1 + x_2 + \cdots + x_n}{n}\]

For example:

  • Mean of [2, 4, 6, 8] = (2 + 4 + 6 + 8) ÷ 4 = 5
  • Mean of [1, 1, 2, 3, 5] = (1 + 1 + 2 + 3 + 5) ÷ 5 = 2.4

The arithmetic mean is used in:

  • Statistics and data analysis
  • Grade point averages
  • Financial calculations
  • Scientific measurements
