- 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 (SD) 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 is spread out from their average value

The variance is a measure of variability It is calculated by taking the average of squared deviations from the mean Variance tells you the degree of spread in your data set The more spread the data, the larger the variance is in relation to the mean Why does variance matter?

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

‘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

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 is the measure of how the data points vary according to the mean, while standard deviation is the measure of the central tendency of the distribution of the data Variance and Standard Deviation The major difference between variance and standard deviation is in their units of measurement
