Write a function that determines standart deviation of float array. The function takes dataset as a float array parameter!! And it also return result as a float. (Clue: calculate average first) www WA Definations: 150 (xi 72 e= standard deviation xi = each value of dataset www WAVAA x with a bar over it) = the arithmetic mean of the data (This symbol will be indicated as average of dataset) N = the total number of data points (if you need square root of some number you can use sort function in math.h library. Usage example: a=sqrt(); which means "a" is equal to square root of "b") w
