In contrast, the arithmetic mean is the correct tool for averaging test scores, temperatures in a stable environment, or the number of customers per day, where the events are independent and not compounding. The arithmetic mean adds values and divides by the count, treating each observation as independent.
Geometric Mean CAGR Calculation Method Explained
When calculating the average factor by which an investment grows annually over five years, the geometric mean is essential. The geometric mean multiplies values and takes the nth root, accounting for compounding effects inherent in multiplicative scenarios.
The gap between the two means expands as the variance, or spread, of the data increases. Using the arithmetic mean for multi-period investments results in an overestimation of actual wealth accumulation, as it ignores the effect of volatility and the compounding process inherent in sequential growth.

Visualization and Data Interpretation. The geometric mean, due to its multiplicative nature and the use of logarithms in calculation, dampens the impact of outliers.
