The standard deviation of a set of numbers is a nonnegative number that measures how tightly the numbers of the set are clustered around the average; the smaller the standard deviation is, the closer the numbers are clustered around the average. If we have n numbers, X1, X2,..., Xn, we can find their standard deviation with the following formula: standard deviation (x1 ) + (x2 ) + + (xr ), n where u is the average (a.k.a. the mean) of the numbers. Write a program that is given an arbitrary amount of numeric command-line arguments and prints their standard deviation to the screen. You can assume that the user will only provide numbers (but not necessarily integers). If the user provides fewer than two command line arguments, the program should print the following error message: usage: java Standard Deviation n1 n2 [n3...] n1, n2, etc.: numbers The standard deviation of a set of numbers is a nonnegative number that measures how tightly the numbers of the set are clustered around the average; the smaller the standard deviation is, the closer the numbers are clustered around the average.
