Challenge Given a list of numbers, calculate the population standard deviation of the list. Use the following equation to calculate population standard deviation: Input The input will a list of integers in any format (list, string, etc.). Some examples: 56,54,89,87 67,54,86,67 The numbers will always be integers. Input will be to STDIN or function arguments. Output The output must be a floating point number. Rules You may use built in functions to find the standard deviation. Your answer can ...
