Arithmetic Mean Calculator



Arithmetic Mean Calculator is an online probability and statistics tool for data analysis programmed to find out Arithmetic Mean of the given data set by taking the sum of the observations and dividing by their number. The mean is often denoted by a little bar over the symbol for the variable, commonly represented as

Definition

The mean is a measure of central tendency value for a distribution. Itís also popularly known as arithmetic mean or average often referenced along with the standard deviation; which describes the central location of the data and the standard deviation describes the spread. An alternative measure of dispersion is the mean deviation, corresponding to the average absolute deviation from the mean. The mean of a set of data x1, x2, ..., xn is typically denoted by , pronounced x bar. This mean is a type of arithmetic mean. If the data set were based on a series of observations obtained by sampling a statistical population, this mean is termed the sample mean to distinguish it from the population mean

The Formula for Mean Calculation

The term in Geometry or Statistics mean can be derived from the formula
