Comparison

  • Geometric Mean: 14.4%
  • Arithmetic Mean: 15%

Interpretation

The geometric mean (14.4%) is lower than the arithmetic mean (15%). This difference occurs because the geometric mean accounts for the compounding effect over the years, providing a more accurate measure of the average growth rate. The arithmetic mean simply averages the percentages without considering how the growth compounds year over year.
