23 23  == 2.2 Experimental Design ==
24 24  
25 -For the experiment, we used a within-subject design, as we did not have enough participants to do a statistically significant between-subject study. To mitigate the transfer effects caused by doing the same activity twice, we had half of the participants starting with the control condition, and half of the participants starting with the test condition.
25 +For the experiment, we used a between-subject design. Two control groups were set up and this allowed us to properly proceed ahead with the evaluation of our research question. The first control group did not interact with the robot at all whereas the second group did. This helped us to avoid bias within our results.
