Formula:
The Quasi Variance, often referring to the biased sample variance, is calculated using the formula:
σ² = Σ(Xᵢ - μ)² / N
- σ²: Quasi Variance
- Xᵢ: Each individual data point
- μ: The population mean (or sample mean, x̄, if population mean is unknown)
- N: The total number of data points in the set
This formula determines the average of the squared differences from the mean, divided by the total number of observations, providing a measure of data dispersion.
