### Subject: Microsoft Excel

How do you find the Standard Deviation of a row of numbers in an Excel sheet?

You find the column you want to find the Standard Deviation. Then, you put in a box below the column =STDEV(E6:E40) or what ever number the row/column the numbers you want. You do =STDEV, and place a bracket. To clarify, you start from the first time the number appears in the list on excel, separated by :, to the last. Then, you close it with a bracket, and click enter. You've got the Standard Deviation for that list!
