Questionnaire None of the ANOVAs for complexity (F(1,14) = 0.358, p = 0.559), accuracy (F(1,14) = 0.071, p = 0.794) and intuitiveness ratings were indicative of relevant differences, yet there was a statistical trend in the within-subjects factor Method of the intuitiveness rating (F(1,14) = 4.230, p = 0.059), whereby participants show a trend to rate the PM-method as being more intuitive than the VAS-method (See Figure 3 ).
