### student activities on the TI-Nspire: Statistics & Probability syllabus topic

Click on the name of an activity in the list below to move directly to the teacher video and TI-Nspire file download for that activity - or simply scroll through the activities/teacher videos below the list. There is a very brief description for each activity, but the best way to gain some insight into the activity is to watch the teacher video. Although the 'type' of each TI-Nspire file is a TI-Nspire CAS Teacher Software Document, it will run on both the CAS and non-CAS version of the handheld device or computer software. If you wish to download all eight of the TI-Nspire activities relevant for the Statistics & Probability syllabus topic in Math SL & HL in one zipped file, you can do that by clicking here.

Standard Deviation
Binomial Distribution
Poisson Distribution Normal Distribution Mean, Median & Standard Deviation - TI-Nspire Activity
interactive dot plots show how changing data values may, or may not, affect values of the mean, median & standard deviation for a set of data; Mean, Median & Standard Deviation - Teacher Video below Standard Deviation - TI-Nspire Activity
interactive visualizations of the underlying concept of the standard deviation for a set of data; and a dynamic diagram showing the set of squared deviations for a set of data; Standard Deviation - Teacher Video below Binomial Distribution - TI-Nspire Activity
binomial distributions illustrated with dynamic histograms where the values of n and p can be changed with the histogram instantly changing as a result; Binomial Distribution - Teacher Video below Poisson Distribution - TI-Nspire Activity – Poisson distributions illustrated with dynamic histograms where the value of the single parameter mu (both mean and variance) can be changed with the histogram instantly changing as a result; Poisson Distribution - Teacher Video below Normal Distribution - TI-Nspire Activity
dynamic normal distribution curve such that the mean and standard deviation can be changed showing the corresponding effect on the curve; Normal Distribution - Teacher Video below
