Answer 1

Step-by-step explanation:

The arithmetic mean is the ‘average’ most people know about: for a set of n numbers, we add them up and divide by n. It’s appropriate for numbers that are relatively evenly distributed, or which follow a normal distribution. For example, if you’re rolling a normal die, the expected value is the mean of all the numbers on it.

The geometric mean is similar, but instead of adding, we multiply the numbers and take the nth root. It’s appropriate for numbers that are distributed along a logarithmic scale - that is, when you’re as likely to find a number twice the size as a number half the size.

The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals of the set of numbers.
