What is an Average?

An average (or mean) is a single value that represents the central tendency of a set of numbers. It's calculated by adding all values together and dividing by the count of values. Averages are fundamental in statistics, finance, education, and everyday decision-making.

Key Formulas

Basic Average: (x₁ + x₂ + ... + xₙ) ÷ n

Percentage Average: (p₁ + p₂ + ... + pₙ) ÷ n

Weighted Average: (w₁x₁ + w₂x₂ + ... + wₙxₙ) ÷ (w₁ + w₂ + ... + wₙ)

x = Values, w = Weights, n = Count

Pro Tip:

Weighted averages are essential when values have different importance—like calculating GPA (courses have different credit hours) or portfolio returns (investments have different sizes). Always match each value with its correct weight!
