An example tutorial on a TI Plus CE graphing calculator calculating standard deviation using one list. An example tutorial on a TI Plus CE graphing calculator calculating standard deviation using two lists. Standard deviation can be calculated by using the stdDev function, sd on ti 84. Follow the examples listed below to calculate standard deviation of one and two lists of data.
Note: The s x variable will not have a value stored to it unless a 1-Var or 2-Var Stats analysis is performed first. Note: The variance command will find the sample variance which is the sample standard deviation of x raised to the power of 2. Please see the TI Plus Family guidebooks for additional information.

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!

In statistics, standard deviation is the square root of the variance. It provides a way of showing how data varies or how it is spread out in a distribution. Standard deviation tells you how much of the data lies within a certain area. Standard deviation can be tricky to calculate by hand, as it requires multiple steps. The TI 84 Plus graphing calculator eliminates those steps and calculates standard deviation with just a few keystrokes. If you get an error, make sure you entered both sets of brackets to get your answer. This part is commonly overlooked.
