The experimental design was a 2x3 between-subject factorial design with repeated measures in the second factor. The first factor was represented by the kind of intervention students received while working with the online tutorial. It was called degree of interactivity. Students in the dynamic test group (n = 21) were able to interact with statistical graphs using numerical input fields. Students in the static test group 1 (n = 18) could only inspect the statistical graphs but could not change the graphs. Further details about the interaction will be explained in the material and apparatus section. The second factor was the time when students were asked about their statistical knowledge: pretest, immediate post-test and delayed post-test.
