The traditional teaching-learning method versus multimedia technology. Using the Wilcoxon test and the Gauss repartition

This article highlights the ways of applying various statistic methods with the purpose of comparing modern teaching methods, which are based on the implementation of information technology, with the traditional teaching methods, tested, for a period of two years, in parallel groups: experimental and control groups. Thus, the Wilcoxon(T) test is used for processing data in case of exams and a creativity task within the experimental and the control groups. This test applies in case of comparing ordinal dependent values and is used with the purpose of determining the correlation of indexes, within one and the same selection, measured in two distinct situations. Outlining the results is done with the help of Guassian comparative curves for both groups (experimental and control).
