When a sample of data \(X_1, X_2, ., X_n\) is given, the sample variance measures the dispersion of the sample values with respect to the sample mean. How do You compute the sample variance? More specifically, the sample variance is computed as shown in the formula below: \[ s^2 = \displaystyle \frac{1}{n-1} \sum_{i=1}^n (X_i - \bar X)^2 \] Range, Standard Deviation, and Variance Calculator. This range, standard deviation, and variance calculator finds the measures of variability for a sample or population. First, the calculator will give you a quick answer. Then it will guide you through a step-by-step solution to easily learn how to do the problem yourself.
