Question

the difference between geometric mean and harmonic mean of 2 and 6is
​

Answer 1

Step-by-step explanation:

The arithmetic mean is appropriate if the values have the same units, whereas the geometric mean is appropriate if the values have differing units. The harmonic mean is appropriate if the data values are ratios of two variables with different measures, called rates.

Answer 2

Step-by-step explanation:

The geometric mean is a type of average , usually used for growth rates, like population growth or interest rates. While the arithmetic mean adds items, the geometric mean multiplies items. Also, you can only get the geometric mean for positive numbers.

Like most things in math, there’s an easy explanation, and there’s a more, ahem, mathematical way of stating the same thing. Formally, the geometric mean is defined as “…the nth root of the product of n numbers.” In other words, for a set of numbers {xi}Ni=1, the geometric mean is:
