Standard deviation versus variance
WebbThe standard deviation is a measure of how close the numbers are to the mean. If the standard deviation is big, then the data is more "dispersed" or "diverse". As an example let's take two small sets of numbers: 4.9, 5.1, 6.2, 7.8 and 1.6, 3.9, 7.7, 10.8 The average (mean) of both these sets is 6.
