How to Create a Histogram and Box Plot on an Online TI-84

The data tells a story, and visualizations like histograms and box plots are its language. Using a free online TI-84 emulator, you can quickly transform a list of numbers into powerful graphs. This step-by-step guide will walk you through the entire process, from entering your data to customizing and interpreting your final charts.

Step 1: Entering Your Data into a List

Watch the [STAT] button on the virtual keypad. Select 1. Edit… to launch the list editor. Enter carefully your set of data into a list, usually L1. Write each three and press [ENTER] between each number. Make sure that the data is entered in a right manner because the quality of a graph is determined completely by it.

Step 2: Accessing the Plot Menu

Hit the [2nd] key and then [Y=] (which is the STAT PLOT key). This brings out the plot menu. You will notice a couple of plot options available. To select Plot1, highlight it and hit [ENTER]. Here you will define the type and settings of your graph. If you make a mistake while entering, here’s how to clear current entry (Quick CE) on a TI-84 calculator

Step 3: Turning On and Configuring Your Plot

When Plot1 has been selected, press [ENTER] to put it On. Then, press the arrow keys in order to get to Type field. To achieve a histogram, select the icon that resembles bars (histogram), and to get a box plot, select the icon which has box and whiskers (box plot). Make sure you have Xlist designated to the list which has your data (e.g., L1). Set Freq 1.

Step 4: Setting an Appropriate Viewing Window

A false window will cover your graph. Click the [WINDOW] key. In a histogram, you need to specify Xmin, Xmax, and Xscl, defining the bar width. A good first step is to place Xscl to any reasonable value between the range of your data set. The calculator generally sets the window automatically, but you can change the Ymin and Ymax values to correct it.

Step 5: Generating and Viewing Your Graph

A false window will cover your graph. Click the [WINDOW] key. In a histogram, you need to specify Xmin, Xmax, and Xscl, defining the bar width. A good first step is to place Xscl to any reasonable value between the range of your data set. The calculator generally sets the window automatically, but you can change the Ymin and Ymax values to correct it.

Step 6: Switching Between Graph Types

It is not difficult to generate both graphs out of the same data. On [STAT PLOT] ([2nd] [Y=]), select Plot1 and change the Type. Go to the Press [GRAPH] to view the new graph. This lets you easily contrast the various views of the distribution of your data.

Troubleshooting Common Graphing Issues

You may have an empty graph, which means that either Plot1 is Off or that other plots are On. Adjust your [WINDOW] as appropriate to the range of values in your data, with the min smaller than your smallest data value, the max greater than the largest. In addition, check your data is accordingly entered in the specified list. For a step-by-step tutorial, read this guide on Mastering the TI-84 Online Calculator
