What is arithmic mean?

The arithmetic mean, commonly referred to as the average, is a measure of central tendency calculated by summing a set of values and dividing that sum by the number of values. It provides a way to represent a typical value in a dataset. For example, the arithmetic mean of the numbers 2, 3, and 5 is (2 + 3 + 5) / 3 = 3.33. It is widely used in statistics and everyday calculations but can be affected by extreme values (outliers) in the data.
