Hint:

Step 1) Find the mean

Step 2) Find the differences of the mean from each data value

Step 3) Square each difference

Step 4) Add up those squares

Step 5) Divide that sum by n-1 (where n is the number of numbers in the data set)

Step 6) Take the square root of the result from step 5 to get the standard deviation


Alternatively, you can use a calculator to calculate the standard deviation.
