Geometric mean is a type of average that indicates the central tendency or typical value of a set of numbers by calculating the nth root of the product of n numbers. It's commonly used in situations where the data has a wide range of values or when the data is not normally distributed, like calculating average growth rates or finding a representative value for a set of numbers that have different scales.

How to use it in a sentence

• "I was trying to calculate the average growth rate of our startup's user base, but then I remembered that the geometric mean is better suited for this since the growth has been exponential, not linear. Time to dust off those old math skills!"

• "When comparing the performance of different computer systems, using the arithmetic mean of benchmark scores can be misleading due to outliers. The geometric mean provides a more accurate representation of overall performance, much like how the 'average' tech bro's coding skills are often exaggerated."
