### Why is geometric mean not negative?

And clearly, it is a positive number. Hence, a geometric mean cannot be negative because we can only use the formula of geometric mean for positive numbers. Note: We need to focus on the fact that we cannot find out the geometric mean of a negative number also, we cannot find the square root of a negative number.

Why geometric mean is always positive?

The geometric mean would be the solution to the following: This means that a, b, and c are usually already results of an exponential, and because any result of an exponential (in ) is positive, you are likely using positive numbers for a, b, and c.

#### Why is the geometric mean used?

The geometric mean is used in finance to calculate average growth rates and is referred to as the compounded annual growth rate. Consider a stock that grows by 10\% in year one, declines by 20\% in year two, and then grows by 30\% in year three.

What is the difference between mean and geometric mean?

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.
