The arithmetic mean is often known simply as the mean. It is an average, a measure of the centre of a set of data. The arithmetic mean is calculated by adding up all the values and dividing the sum by the total number of values. Arithmetic mean or simply the mean of a variable is defined as the sum of the observations divided by the number of observations.
Mean, also known as the average, is a mathematically calculated number that represents the central tendency of a list of numbers. It is calculated by adding all of the numbers in a list and then dividing by how many numbers are in that list.
The arithmetic mean can be used to compare two sets of data. If one set of data has an arithmetic mean that is greater than the other set’s, it means that the first set has more values higher than any value in the second set.
In this section, we will go through a few examples of arithmetic mean.
The arithmetic mean is the sum of all values in a set of numbers divided by the number of values in the set. The following are some examples of arithmetic mean calculators:
If you have the following list: {1, 2, 3} then the arithmetic mean would be (1+2+3) / 3 = 2.
The arithmetic mean of 1, 2, 3, 4 and 5 is 2.
The arithmetic mean is the simplest calculation to determine the average return. The average return on an asset, observed over a long period of time, is often used as the expected return for future years. Although the future return is unknown and cannot be predicted with great accuracy, the historical average return is as good a guess as any of what the return will be in the future.
