# How do you find arithmetic average?

## How do you find arithmetic average?

One method is to calculate the arithmetic mean. To do this, add up all the values and divide the sum by the number of values. For example, if there are a set of “n” numbers, add the numbers together for example: a + b + c + d and so on. Then divide the sum by “n”.

The geometric mean differs from the arithmetic average, or arithmetic mean, in how it is calculated because it takes into account the compounding that occurs from period to period. Because of this, investors usually consider the geometric mean a more accurate measure of returns than the arithmetic mean.

### How do you find arithmetic average percentage?

#### Should I use arithmetic or geometric mean?

Each mean is appropriate for different types of data; for example: If values have the same units: Use the arithmetic mean. If values have differing units: Use the geometric mean. If values are rates: Use the harmonic mean.

#### Which is better arithmetic or geometric mean?

The arithmetic mean is more useful and accurate when it is used to calculate the average of a data set where numbers are not skewed and not dependent on each other. However, in the scenario where there is a lot of volatility in a data set, a geometric mean is more effective and more accurate.
