Webinar on statistical tests and sample size: presentation materials
XLSTAT was proud to present its second free short Webinar (May 14). After briefly describing the principles of statistical testing, we talked about the difference between parametric and nonparametric statistical tests. Then, we proposed rules of thumb for sample size before running a demo on XLSTAT in which we compared the outputs of a 1-way ANOVA to the output of its nonparametric equivalent, the Kruskal-Wallis test.
