This presentation is meant to remind students how to apply statistics for the internal assessment.
A helpful site for the calculation of the statistics is Vassarstat. To find the non-parametric tests, go to the "Ordinal data" link in the left-hand column. If you use this site to calculate the statistics, students are required to print out the calculations and include them as an appendix in their report.
