Understanding Variance
Variance measures the average squared deviation from the mean. A high variance indicates that the data points are very spread out from the mean, while a low variance indicates that they are clustered closely around the mean.
Population Variance
Population variance is calculated when you have data for the entire population.
Sample Variance
Sample variance is calculated when you have data for a sample taken from the population.
Formula for Population Variance
σ² = Σ (xi - μ)² / N
Formula for Sample Variance
s² = Σ (xi - x̄)² / (n-1)
