259 259  We analyzed the participants' moods before and after the interaction with Pepper in order to be able to observe positive and negative changes that are caused by the interaction with Pepper. The hypothesis H0 is that Pepper does not have any effect, which would mean that the questionnaires 1 and 2 should give the exact same values for each of the six feelings. However, the graphs and table below show that there is a slight increase regarding positive feelings, and a slight decrease as well regarding negative feelings. The Wilcoxon Signed-rank demonstrated that the only statistically significant change happened for contentness and tiredness based on a p-value threshold of 0.05.
