def compute_stdev(a_list): """ What it takes? a list of numbers what it does? given a list of numbers compute the standard deviation

(find the formula for standard deviation online if you dont remember it)

Here are the steps that you will follow:

1. find the mean of the numbers 2. subtract the mean from each numbers 3. square the differences 4. sum the differences 5. divide by (the size (len) of the list - 1) if there are 5 items in the list, divide it by 4 6. take the square root of the result 7. return it what it returns? a number (float), which is the standard deviation """ # your code goes in here return
