Mean Calculator

Dataset set
comma separated input values
Number of samples  =  5
Root mean square  =  12

Sample or Population Mean - work with steps

Input Data :
Data set = 5, 8, 12, 15, 20
Total number of elements = 5

Objective :
Find what is mean value for given input data?

Formula :
formula to calculate sample or population mean

Solution :
Mean Value = 5 + 8 + 12 + 15 + 20/5
= 60/5
Mean = 12

Arithmetic mean calculator online probability & statistics data analysis tool to find the mean or average or expected value or center value of the sample or population data set by taking the sum of the observations and dividing by their total number of instances. In statistics, the mean is often referenced along with the standard deviation and denoted by a little bar over the variable, commonly represented as 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 x1, x2, ..., xn is typically denoted by , 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 Formula for Mean Calculation

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