Thank you for the opportunity to help you with your question!
You need to square each of the numbers Your list of squares is 441,441,225,324,225
One less than this is 5-1 = 4.
The sum was 1656, and the number from the previous step was 4. You divide these two numbers 1656/4 =41 4.
I am still confused bc I got a larger number too but these are my options. Did I miss a step? 3.0, 6.0, 2.4, 3.9
yes it means that you missed a step,because the value you gave as differences already implies that you have subtracted the values from the mean which is the first step in calculating the sd....then the other steps follow systematically
OK that is the problem as written and the answers so I will try and figure it out.
