Explain VARIANCE: “How much a list of numbers varies from the mean (average) value. It is frequently used in statistics to measure how large the differences are in a set of numbers. It is calculated by averaging the squared difference of every number from the mean.”[segaran] Any statistical package will offer an automated way to calculate this. See also mean, bias, standard deviation.
