The STD Of A Series Of Numbers

I have designed a function that calculates the STD of a series of numbers.



I need to design a test function that takes a 2D array as an input (numbered colorful balls sample numbers found below), calls my deviation function, and displays the calculated STD (in 2 decimal places) for each color in the group of lists. Then it creates a new list as shown below with the color and STD of the list.
