Rule Variance Definition. In particular, it measures the degree of dispersion of data around the sample's mean. Variance is a statistic that is used to measure deviation in a probability distribution. The variance is a measure of variability. Here, the variance of $y$ is quite small since its. Variance is a measurement of the spread between numbers in a data set. It assesses the average squared difference between data values and the mean. The variance of a discrete random variable, denoted by v ( x ), is defined to be. Deviation is the tendency of outcomes to differ from the expected value. Unlike some other statistical measures of. Variance of a random variable is called its standard deviation, sometimes denoted by sd(x). The variance is a measure of how spread out the distribution of a random variable is. It is calculated by taking the average of squared deviations from the mean. That is, v ( x) is the average squared distance. The variance of a random variable xis unchanged by an added constant: Variance is a measure of variability in statistics.
