Variance
Measure the absolute dispersion and inconsistency of the numerical samples.
9 detected values
Variância Amostral (s²)750
Formula
Σ(x - x̄)² / (n - 1)
Step by Step
Média: 50.0000
Soma dos quadrados das diferenças: 6000.0000
Divisor (n-1): 8
Variância = 6000.0000 / 8 = 750.0000
The Measure of Chaos
You bought a machine that fills 1kg bags. If the calculated Variance of your samples is very high, it means that one bag comes out with 800g and another with 1.2kg (an industrial chaos)! The closer the variance is to zero, the more standardized your data are.
