The geometric mean is often favored in economic price analysis because it is particularly useful when dealing with rates of change, such as in financial data where prices can fluctuate significantly. This mean is calculated by multiplying the values together and then taking the nth root, where n is the number of values. This method effectively captures the multiplicative nature of percentage changes over time, making it better suited for understanding the average rate of return or growth rates across different time periods.

For example, if analyzing the average price increase over multiple years, the geometric mean accounts for the compounding effect inherent in such data. In contrast, other means like the arithmetic mean could provide skewed results in cases with extreme values, while the median only captures the middle value and may not reflect the overall price dynamics accurately for distributed data. Moving averages, while helpful in smoothing data over time, are not a mean in the same sense; rather, they are a technique applied to trends rather than a singular measure of central tendency like the geometric mean.
