Our Population Variance Calculator helps you quickly determine the statistical spread of an entire population dataset. Input your data points to find how much individual values deviate from the mean, ensuring accurate demographic, scientific, and economic analysis. Understand population variability with ease and precision.
Formula:
The formula for population variance (σ2) is:
σ2 = Σ (xi - μ)2 / N
- σ2: Population Variance
- Σ: Summation (sum of all)
- xi: Each individual data point in the population
- μ: Population Mean (the average of all xi values)
- N: Total number of data points in the population
This formula measures the average of the squared differences from the population's mean, indicating how dispersed the data points are.
