255 255  The hypothesis H0 is that Pepper does not have any effect. In this case, 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 sligt decrease as well regarding negative feelings.
256 256  There are however many biases in these results. The main one that we isolated is that the activity of gardening itself could lead to the mood improvement. For this reason, we made subgroups based on whether the participants liked gardening or not.

561 561  * Scope: No. It would be very difficult to generalize the results, since each prototype is built for a special patient. However, if the results conclude that the customized prototypes did improve the well-being of the people, then similar effort to customize Pepper for more patients should produce similar effects.
562 562  * Ecological validity: Yes. Since we compare "without Pepper" (BEFORE) and "with Pepper" (AFTER) in a similar environment (i.e., for everything but Pepper), the results are not dependent on the environment.

575 +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 pepper. the results showed that, in general, there is a slight increase in positive moods and a slight decrease in negative moods. 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. This confirms that PwD can potentially benefit from a boost of energy from interacting with Pepper and a general improvement in contentness wich can potentially improve the quality of life of a PwD. It is often the case that PwDs have to perform tasks that are not enjoyable for them such as taking medicines or performing routine activities. In order to analyze the difference in the mood change between people who liked the activity and people who didn't we divided 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 which leads us to believe that if an activity is not enjoyable for the PwD Pepper will only decrease his/her tiredness whereas if an activity is enjoyable it will also improve his/her contentness.

566 566  The results from the mood questionnaire seem to support our claims CL10: the PwD feels reassured and CL11: the PwD feels content.
