What is the Arithmetic Mean?
The Arithmetic Mean, often just called the "mean" or "average," is the sum of a collection of numbers divided by the count of numbers in the collection.
Formula
Mean = (x₁ + x₂ + ... + xₙ) / n
When to use the Mean
Use the mean when you want an overall snapshot of the data, provided there are no extreme outliers (very large or very small numbers compared to the rest). If outliers exist, the Median might be a better measure.
