The HPO Stat module allows you to evaluate a process and measure the impact of a training or simulation device by applying valid statistical models. The Wilcoxon test, one of the proposed models, allows you to compare two related groups of data, even in the case of non-normal distribution or small sample size. It can be used to evaluate the effectiveness of a new strength training program, the improvement in shooting accuracy during a training session, or the variation in memory performance depending on the time of day. HPO Stat is integrated into our solutions and allows you to trigger different functional or evaluation tests to compare the evolution of results over time.
