You can find the standard deviation of a data set in two ways with your TI-84 Graphing Calculator. First, have a look at the long lists to calculate the standard deviation from scratch on the TI-84 Graphing Calculator. Then see how to quickly find the standard deviation using one-variable stats. To help your understanding of standard deviation, this video explains what the abbreviations mean and where you can access these variables in your TI-84 Graphing Calculator.

The Ti-84 Plus calculator can handle three decision commands (If, If . . . Then . . . End, and If . . . Then . . . Else . . . End). Here is how to use these commands in a program.The If commandThe structure of the If command appears in the first screen. If the condition following the If command is true, the program executes the command following the If statement (Command 1) and then moves on to the next command in the program (Command 2).

The TI-84 Plus C graphing calculator is one of the most popular calculators in the world. Find out the important keystrokes you need to know to use the TI-84 Plus, and learn the math functions and constants that the TI-84 Plus C makes available to you.Get to know the basics of graphing on your TI-84 Plus C, as well as how to use the calculator’s zoom commands and special menus.

Your TI-89 graphing calculator (along with the TI-89 Titanium, TI-92 Plus, and Voyage 200) help you graph and so much more. You can do higher math functions, include symbols, and format equations as well as make use of the basic calculator functions — and some odd ones, too!How to find higher math functions on the TI-89 graphing calculatorOf course, your TI-89 graphing calculator helps you with higher math functions — that’s part of the reason you bought it.

Even the best calculating machine is only as good as its input. This list identifies ten common errors made when using the TI-84 Plus calculator. Wouldn’t it be great to avoid some of the common errors that normally plague students who are using calculators?Using [–] instead of [(-)] to indicate that a number is negative.

On the TI-84 Plus calculator, it's difficult to get a nice viewing window for your sequence on your first attempt. Understanding the basics of sequence notation should help. Here are the variables used in the window of a sequence graph: nMin: Where n starts counting. 1 is the default value. nMax: Where n stops counting.

A piecewise function is actually made up of “pieces” of different functions. Each function “piece” is defined over a certain interval. Using your TI-84 Plus calculator to graph piecewise functions can be a bit tricky, but you’ll get the hang of it soon enough. Your calculator evaluates statements and produces one of two possible truth values: 1 = True and 0 = False.

The ZStandard, ZDecimal, ZTrip, and ZQuadrant1 zoom commands help you initially graph or regraph your function in a preset viewing window. To use these zoom commands, enter your function into the calculator, press [ZOOM], and then press the key for the number of the command. The graph automatically appears. ZStandard zoom command on the TI-84 Plus This command graphs your function in a preset viewing window where You access it by pressing [ZOOM][6].
