Understanding averages
The arithmetic mean is the familiar average: add all values and divide by the count. It works well for balanced data without extreme outliers.
The geometric mean multiplies values and takes the nth root. It is used for growth rates, ratios, and values that scale multiplicatively.
The harmonic mean averages rates, such as speed or price per unit. It gives more weight to smaller values, which is useful for rates and densities.
Choosing the right mean depends on the data. Use arithmetic for totals, geometric for growth, and harmonic for rates.
