# Sample Mean Calculator

Sample mean and Sample covariance is an estimate of the population mean(mu) and population covariance. Population here refers to the set from which the sample was taken. It is otherwise called as empirical mean. It is a statistics found from a collection (the sample) of data on one or more random variables. It is nothing but the arithmetic average of the sample values. Use the online sample mean calculator to estimate the mean of a sample and total numbers.

## Estimate Mean of a Sample

Sample mean and Sample covariance is an estimate of the population mean(mu) and population covariance. Population here refers to the set from which the sample was taken.

#### Formula:

x̄ = ( ∑ xi ) / n Where, x̄ = Sample Mean xi = 'x' values n = Number of Samples

### Example:

Find Mean of a Sample 13,23,12,44,55

#### Solution:

x̄ = ( ∑ xi ) / n
= (13+23+12+44+55) / 5
= 29.4
