Nosignificant interaction found for the Control Group as regards to paper quality. ChiSquare.This data reflects the fact that the interaction between the questions asked and thequality of paper applies only to children in the Experimental group. From theanalysis shown in table 2 we know that such interaction is negative (meaning that askingmore questions may actually lower the quality of paper).In order to gain a better understanding of the interaction between the quality of the paperand the questions asked to the expert, we have first looked at how the average numberof questions asked, with respect to a specific paper quality varied between theExperimental and Control group. Figure 4 shows that not only children in the Controlgroup asked significantly less questions on average, but also that the trend to a positiveinteraction between the number of questions asked and paper quality present in thecontrol group, reverses in the Experimental group.Del 4.4: AtGentive Final Evaluation Report – Appendix C page 9
