Step 1

Variance is a statistical measurement that describes the spread of data points in a data distribution. It measures how far each number in the set is from the mean (average) and thus from every other number in the set. Variance is often denoted by the symbol Show more…

Key Concepts

Variance

Variance is a statistical measure that quantifies the dispersion of a set of data points around their mean by calculating the average of the squared differences from the mean. It gives a sense of how much the data points differ from the average value, but because it involves squaring the deviations, its units are the square of the original measurements.

Standard Deviation

Standard deviation is a measure that indicates the amount of variation or dispersion in a data set. It is defined as the square root of the variance, which converts the squared units of variance back to the original units, making it more directly interpretable in the context of the data.
