Question: Write a method stdev that computes the standard deviation of an array of real numbers. The formula for computing a standard deviation of N

Write a method stdev that computes the standard deviation of an array of real numbers. The formula for computing a standard deviation σ of N values is the following, where x_i represents each i^th element and μ represents the arithmetic mean (average) of all the elements:

N 1 O = (x; – µ)? N i=1

N 1 O = (x; )? N i=1
