Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? In an experimental case study, regression analysis indicated that TimeOnTask explains up to 76.2% of the variance in engagement change. → Ghergulescu 2016

q2 · i? · design · r2
Experimental case study with 50 participants playing the Fire Protocol educational game while wearing an Emotiv EPOC headset; regression analysis indicated TimeOnTask "explains up to 76.2 % of the variance in engagement change."
"The results of an experimental case study show that the proposed ToTCompute mechanism can be used to automatically compute threshold values for the TimeOnTask generic engagement metric, with regression analysis indicating that TimeOnTask explains up to 76.2 % of the variance in engagement change."
