WebThe 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. WebHence, the standard deviation can be found by taking the square root of variance. Therefore, standard deviation = √variance. Standard deviation = √ (9.25) = 3.041. Hence, the mean, variance and standard deviation of the given data are 9, 9.25, 3.041 respectively. Thus, these are the key differences between variance and standard …
