Average Types - Brief Explanation

Arithmetic mean – The sum of all values divided by their number. The most popular measure of average.
Median – The middle value in the sorted data set. Divides the set into two equal parts, resistant to extreme values (so-called outliers).
Geometric mean – The square root of degree N of the product of N numbers. Mainly used in finance (e.g. rates of return) and population growth statistics.
Harmonic mean – The ratio of the number of data to the sum of the reciprocals of this data. Useful for calculating average speeds, efficiency or ratios.

What is the arithmetic mean

The arithmetic mean is one of the basic statistical measures, often called simply the mean. It determines the average value in a data set and helps you quickly see what level the numbers cluster around. If you only know individual values, it is difficult to assess the overall picture, but the arithmetic mean collects them into one simple summary.

The definition of the arithmetic mean is:

arithmetic mean = (x1 + x2 + ... + xn) / n

In other words, you add all the values and then divide the sum by their number. The average calculator does this automatically, so you don't have to keep track of all the steps yourself.

How to calculate the arithmetic mean using the Average Calculator

Calculating the arithmetic mean using a calculator is easier than calculating on a piece of paper or in a spreadsheet. You just need to follow a few steps that are the same regardless of whether you calculate the average of 5 assessments or 50 measurements.

Step by Step
