Randomly distributed points: no variables
have yet been assigned.
One of the six core applicaons of TI-Nspire is Data & Stascs, the workspace for presenng, interpreng and
manipulang stascal charts and graphs. This applicaon works in combinaon with the Lists & Spreadsheet
applicaon and this tutorial uses the data that were entered as a spreadsheet at the beginning of Tutorial 6.
Start by locang in your Document the page that you created
in the rst part of Tutorial 6. There should be 20 or 30 pairs of
(probably cous) data in columns A and B and at least 15
values in column C.
• List in column A represents male shoe sizes.
• List in column B has widths of hand spans in cm
(paired data with column A).
• List in column C represents female shoe sizes.
To create a new page for the charts press c then select .
Move the cursor to the boom of the screen where it says:
Click to add variable. Press x.
A list of currently dened lists opens up, so use the Touchpad
to select and press · or x.
Inially you will see a dot plot.
Press b1 to see the Plot Type menu, which gives nine
types of plot. Because you have only dened a single
numerical variable so far, there are only three alternave
plots including a boxplot and a histogram.
