The arithmetic mean, also known as the average, is calculated by adding up all the values in a dataset and then dividing by the total number of values. It is a measure of central tendency that is sensitive to extreme values, making it less robust than the median. The arithmetic mean follows the properties of linearity, meaning that it can be distributed across sums and differences in a dataset. Additionally, the sum of the deviations of each data point from the mean is always zero.
