Calculus and Statistics Methods
Variance is a statistical measurement that describes the dispersion or spread of a set of data points in relation to their mean. It quantifies how much the values in a dataset deviate from the average value, providing insight into the variability within the data. Understanding variance is crucial when working with probability distributions, random variables, and measures of central tendency, as it helps to characterize the distribution's shape and predict outcomes based on data variability.
