##### TI-Nspire For Dummies

On the TI-Nspire, you scan perform some basic statistical functions on a single data set. Assume that you’ve entered the first-semester averages for two Algebra II classes in a column titled algebra2, and you’re interested in performing a one-variable statistical analysis on this data.

Here are the steps:

2. Press [ENTER] to indicate that you want to analyze one list.

If you have additional lists, change the Num of Lists field to match the number of lists that you are interested in analyzing.

3. Configure the dialog box as shown.

Scroll down column C to review the statistical results that are generated by this action. The following list contains a description of what each result means:

• Sample mean,

• Sum of the data,

• Sum of the squared data,

• Sample standard deviation, sx

• Population standard deviation,

• Sample size, n

• Minimum value, MinX

• First quartile, Q1X

• Median, MedianX

• Third quartile, Q3X

• Maximum value, MaxX

• Sum of squared deviations, SSX

You also could have created a separate list for each Algebra II class, one in column A and one in column B. To do this, press [MENU]→Statistics→Stat Calculations→Two-Variable Statistics to obtain the single-variable statistics for both classes simultaneously.
