variance online

#### Description :

The online variance calculator determines the variance of a series of value. The variance is calculated from the average. The online calculator is able to calculate the variance of a set of values with the steps of the calculations. The variance calculator supports numeric but also literal expressions. The calculator can use the frequency value of the series.

# Variance calculation online

It is possible to calculate the variance of the following series of numbers : 12;32;45;34, for this, enter variance([12;32;45;34])

It is also possible to calculate the variance of the following numbers: 12;32;45;34 whose frequency 3;5;3;2, enter variance([[12;32;45;34];[3;5;3;2]])

# Variance symbolic calculation online

The variance calculator is able to calculate the variance of a series of literal expressions, the result is returned in exact form and details of the calculations are specified.

It is possible to calculate the variance of the following elements 3a; 6a; 7a, for this, enter variance([3a;6a;7a]), after calculation result is returned with calculation steps.

It is possible to compute the variance of the following elements 3a;6a;7a whose frequency 3;5;3;2 after calculation result is returned with steps of calculations, for this enter variance([[3a;6a;7a];[3;5;3;2]]).

#### Syntax :

• variance([s1;s2;...;sn]), s1, s2, ..., sn are a series of numbers
• variance([[s1;s2;...;sn];[f1;f2;...;fn]]), s1, s2, ..., sn are a series of numbers, f1; f2, ..., fn represent the frequencies of these numbers.

#### Examples :

variance([1;9;7]), returns 104/9
