 # How To Use GEOMEAN()

Description

Calculates the geometric mean of a dataset.

Common questions about the GEOMEAN formula include:
- How do you calculate a GEOMEAN?
- What do the GEOMEAN and the arithmetic mean have in common?
- What is the best method for calculating a GEOMEAN?

The GEOMEAN formula can be used appropriately to calculate the length-weighted average of a number of results, rather than the arithmetic mean of a set.

The GEOMEAN formula can commonly be mistyped as GEOM MEAN, GMEAN, or GEOMAEN.

Common ways the GEOMEAN formula is used inappropriately include using range data of different types (e.g. text and numbers) or using data of different ranges or data points with weights.

Common pitfalls when using the GEOMEAN formula include not understanding the significant differences between the GEOMEAN and the arithmetic mean. Using data points that are of common type and in the same range is also important for accurate calculation of the GEOMEAN.

Common mistakes when using the GEOMEAN formula include miscalculating the GEOMEAN due to errors in data entry, not appropriately understanding the differences between GEOMEAN and arithmetic mean, or not understanding the differences between GEOMEAN and weighted mean.

Common misconceptions people might have with the GEOMEAN Formula include not understanding that the GEOMEAN can only be calculated using numbers, or not understanding that the GEOMEAN is length-weighted which produces a different outcome than the arithmetic mean.
