Find the Standard Deviation With a Graphing Calculator (TI83 or TI84) Step 3: Select the correct standard deviation. Now we have to be very careful. There are two standard deviations listed on the calculator. The symbol Sx stands for sample standard deviation and the symbol σ stands for population standard deviation. If we assume this was sample data, then our final answer would be s =2.71. Pay attention to what kind of data you are working with and make sure you select the correct one!
