- Variance - Wikipedia
In probability theory and statistics, variance is the expected value of the squared deviation from the mean of a random variable The standard deviation is obtained as the square root of the variance Variance is a measure of dispersion, meaning it is a measure of how far a set of numbers are spread out from their average value
- Variance - GeeksforGeeks
Variance is a number that tells us how spread out the values in a data set are from the mean (average) It shows whether the numbers are close to the average or far away from it
- What Is Variance in Statistics? Definition, Formula, and Example
Variance is a statistical measurement of how large of a spread there is within a data set It measures how far each number in the set is from the mean (average), and thus from every other number
- How to Calculate Variance | Calculator, Analysis Examples
The variance reflects the variability of your dataset by taking the average of squared deviations from the mean
- Variance: Definition, Formulas Calculations - Statistics by Jim
Variance is a measure of variability in statistics It assesses the average squared difference between data values and the mean Unlike some other statistical measures of variability, it incorporates all data points in its calculations by contrasting each value to the mean
- What is Variance in Statistics? Easy Step-by-Step Guide
The variance (Var) tells you how much the results deviate from the expected value If the variance (σ 2) is large, the values scatter around the expected value

Variance measures the spread between numbers in a data set It helps us determine how far each number in the set is from the mean or average, and from every other number in the set
- Variance - Definition, Symbol, Formula, Properties, and Examples
‘Variance’ refers to the spread or dispersion of a dataset in relation to its mean value A lower variance means the data set is close to its mean, whereas a greater variance indicates a larger dispersion
