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
Dec 19, 2023 · The term variance refers to a statistical measurement of the spread between numbers in a data set. More specifically, variance measures how far each number in the set is...
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.

Jan 18, 2023 · 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.
Variance is a statistical measurement that is used to determine the spread of numbers in a data set with respect to the average value or the mean. The standard deviation squared will give us the variance. Using variance we can evaluate how stretched or squeezed a distribution is.
The meaning of VARIANCE is the fact, quality, or state of being variable or variant : difference, variation. How to use variance in a sentence. Synonym Discussion of Variance.
3 days ago · Variance is a statistic that is used to measure deviation in a probability distribution. Deviation is the tendency of outcomes to differ from the expected value. Studying variance allows one to quantify how much variability is in a probability distribution.
Variance is the average of the squared differences of a random variable from its mean. It is a statistical measurement of variability that indicates how far a set of numbers varies from the mean. A high variance tells us that the collected data has higher variability, and the data is generally further from the mean.
