In statistics, the mean is often referenced along with the standard deviation and denoted by a little bar over the variable, commonly represented as x̄
The mean is a measure of central tendency value for a distribution. It's also popularly known in other few names such as arithmetic mean, average and expected value often referenced along with the standard deviation; which describes the central location of the data and the standard deviation describes the spread. The mean of a set of data x_{1}, x_{2}, ..., x_{n} is typically denoted by x̄, pronounced x bar. This mean is a type of arithmetic mean. If the average or mean is calculated for the sample data then it is named as sample mean. On the otherhand, if it calculated for entire data of population then it is called as population mean
The term in Geometry or Statistics mean can be derived from the below formula
In the field of probability & statistics for data analysis, the usage of mean is in high in demand. When it comes to find or verify the results of arithmetic mean calculations, this online mean value calculator may useful to determine the expected or average value of the given data set.
