259 259  
260 260  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.

328 328  In order to analyze the difference in the mood change between people who liked the activity of gardening and people who did not, we divided the assessments into two groups and performed a Wilcoxon Rank-Sum test. The results show that only the contentness mood shows a statistically significant difference between the two groups. Hence, we did not notice any relevant pattern indicating a significant difference between "like gardening" and "dislike gardening" groups. It seems to be that this is not the cause of the mood improvement.

330 330  This confirms that PwDs can potentially benefit from a boost of energy from interacting with Pepper and, if the activity is enjoyable, a general improvement in contentness as well.

342 -The first group, namely task guidance assessment, contains questions aimed at measuring how easy and pleasant was the activity when being guided by Pepper. The responses for this group are around the slightly agree line, a bit higher for the "Pepper was easy to understand" statement and a bit lower for the "I enjoyed the task more than if I had had to do it alone".
