SUS usability ratings (adapted from Brooke 1996) in the same Paint.NET experiment. The quote reports that ITS usability was "significantly less than that of the book and movie", with printed effect size ω2 = 0.15, which is large by the η²/ω² convention (≥ .14).

"the student 's perception of the ITS’s usability was significantly less than that of the book and movie (Book M=60 .3, SD=10.6; Movie M=60.0 , SD=9.0; ITS M=50.9, SD=8. 7; F(2,71)= 7.611, p=.001, ω2 =0.15)."
