Only the truly insane or those in an introductory statistics course would calculate the standard deviation of a dataset by hand! So what is left for the rest of us level headed folks? Instead, we can use a graphing calculator to perform the exact same calculations. Note: You can scroll down for a video walkthrough of these steps. For this example, we will use a simple made-up data set: 5, 1, 6, 8, 5, 1, 2. This will come up later in the steps. This will be the first step for any calculations on data using your calculator. Now, we can type in each number into the list L1. The entire dataset should go into L1. Now we have to be very careful. There are two standard deviations listed on the calculator. Pay attention to what kind of data you are working with and make sure you select the correct one! The variance does not come out on this output, however it can always be found using one important property:. The following video will walk your through all of these steps. Make sure you have your calculator ready to follow along!
