Arithmetic mean:

Arithmetic Mean, commonly known as the average , is a fundamental measure of central tendency in statistics. It is defined as the ratio of all the values or observations to the total number of values or observations. The mean, often referred to as the average , is a fundamental concept in statistics used to describe the central tendency of a data set. It is calculated by adding all the values in a data set and dividing the sum by the number of values. In Mathematics and Statistics, the Arithmetic Mean (AM) or Mean or Average is defined as the sum of all observations in the given data set divided by the total number of observations in the dataset. The arithmetic mean formula is given as the sum of all observations divided by a number of observations. Understand the arithmetic mean formula with derivation, examples, and FAQs.
