P-Value of 2-way ANOVA in TI Nspire

The TI Nspire CX provided very convenient facility to perform 2-way ANOVA analysis. The P-values are displayed in the spreadsheet as well as being stored in designated variables that can be recalled from the calculator screens and other applications.


As shown above, the last two equations are refresher of how the P-values are determined from the F statistics.

Graphical representation can also be plotted in the Graph application. With the aid of the Integral tool, the shaded area in the below example represents the area from 0 to the F statistics. Recall that the whole area under the curve is 1, the P-value from F statistics to infinity is then 1 – 0.961 = 0.039
