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
