Change Scale and Adjust Bins on a Histogram

You can create a histogram on the TI-Nspire. Press [MENU]→Plot Type→Histogram (or right-click near the middle of the screen and choose Histogram) to display single-variable data as a histogram. The first [more…]

Change Histogram Variables and Insert a Normal Curve

As with a dot plot, you can change variables or use the Add/Remove Variable options located on the [MENU]→Plot Properties submenu on the TI-Nspire. Remember to use the Add/Remove tools to change your histogram [more…]

How to Plot a Value on a TI-Nspire Histogram

On the TI-Nspire, you can plot a value on a histogram that displays as a vertical line perpendicular to the horizontal axis at a point equal to the specified value. In the third screen, press [more…]

How to Work with Box Plots on the TI-Nspire

On the TI-Nspire, you can create box plots. Consider that you want to investigate the major-league home run leaders between the years of 1988 and 2002. Although this topic is somewhat controversial, from [more…]

Box Plot Outliers and the Use of Color on TI-Nspire

To graph a second box plot on the TI-Nspire containing the National League data, press [MENU]→Plot Properties→Add X Variable and choose nl to create the second box plot. [more…]

Raw Data versus Summary Data on TI-Nspire

On the TI-Nspire, categorical data can be represented in two modes of statistical plotting, raw data and summary data. Raw data is contained in one list. Summary data contains separate lists. In this first [more…]

How to Initiate a Data Experiment on TI-Nspire

You can conduct data experiments easily on the TI-Nspire. Consider that you want to collect data on a bouncing ball. Your interest is in observing the successive heights of each bounce of the ball. Following [more…]

How to Replay a Data Experiment on TI-Nspire

On the TI-Nspire, it is easy to replay a data experiment. This is a great feature! You can see an instant replay of your experiment. What a great tool to use in the classroom! To replay an experiment, [more…]

How to Be More Selective with Your Data

Maybe you want to work with only one part of your data. You can be more selective when working with data on the TI-Nspire. For example, you can isolate one parabola from a data experiment involving a bouncing-ball [more…]

How to Analyze Data in Vernier DataQuest

The Vernier DataQuest application for TI-Nspire has many built-in tools that allow you to analyze the data. The Infobox on the left side of the screen shows the Analyze tools that you have chosen to activate [more…]

As with single-variable data sets, on the TI-Nspire you can plot a value on a scatter plot that is displayed as a vertical line perpendicular to the x-axis at a point equal to the specified value. To access [more…]

How to Adjust Window Settings on TI-Nspire

On the TI-Nspire, you can manually adjust the XMin, XMax, YMin, and YMax values by pressing [MENU]→Window/Zoom→Window Settings. Remember to press [TAB] [more…]

How to Manipulate Two-Variable Data on TI-Nspire

As with single-variable data on the TI-Nspire, you have the option of changing data values in the Lists & Spreadsheet application and dragging points directly on a scatter plot. Keep in mind that the two-way [more…]

Scatter Plots in Graphs versus Data & Statistics on TI-Nspire

You may wonder why you would ever use the TI-Nspire Graphs application to graph and analyze two-variable data. Here are two reasons why you may choose to use the Graphs application over the Data & Statistics [more…]

Summary Plot with Two-Variable Data

One interesting feature of the TI-Nspire is that categorical data can be represented with a summary plot. A summary plot is an excellent way to compare two data sets side by side. A group of students were [more…]
