CSG Liudger is a state secondary school in the Netherlands. I have been using TI-Nspire handhelds and software with this group of students since September 2007 and TI-Nspire Navigator since May 2009. In this lesson I used File transfer, Screen Capture and Live Presenter features.
The students were able to use their existing knowledge of statistical variables such as the mean average and the median to confirm or refute their statistical hypotheses. They also considered how the use of different statistical graphs might support this process.
