Answer: standard deviation
is a measure of the amount of variation or dispersion of a set of values.[1] A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust.The standard deviation is given by the formula: s means 'standard deviation'. S means 'the sum of'. Now, subtract the mean individually from each of the numbers given and square the result.

=½×18.7×6.2
=18.7×3.1. [½×6.2=3.1]
=57.97
