How do I calculate the variance population formula manually?
Variance and standard deviation are related but distinct concepts. Variance measures the average of the squared differences between individual data points and the mean, while standard deviation is the square root of the variance, representing the average distance between data points and the mean.
Σ(x - μ)² / N
Reality: Variance measures the spread or dispersion of a dataset, not central tendency.
