# Quasi Variance Calculator

The statistical approach to overcome the reference category is called Quasi-variance. When estimating the effects of a categorical explanatory variable within a statistical model, quasi-variance is used. They are the approximations of variances. In the below Quasi variance calculator enter the values of a data set as comma separated values of any length and submit to know the quasi-variance. For example: QV for a data set of 2,3,4,5,6,6,67 is 563.23.

#### Formula:

qVar = (1 / (n - 1)) Σ(x_{i} - x̄)^{2}
**Where,**
qVar = Quasi Variance
X = Input Value
x̄ = Mean
n = Number of Scores
Quasi-variance (qv) varies according to the data set values. Always while entering the inputs in Quasi variance calculator ensure that you are entering the data in the acceptable format only.
