If you're behind a web filter, Need for Variance and Standard Deviation. We have studied mean deviation as a good measure of dispersion. But a major problem is that mean deviation ignores the signs of deviation, otherwise they would add up to zero.To overcome this limitation variance and standard deviation came into the picture. Standard deviation formula is used to find the values of a particular data that is dispersed.
