Subclaims¶

q3 i? No significant fixed effect of the variance indicator was found on CPS performance (estimate = -1.85, p = 0.155). → Eichmann 2019 q3 i3 A significant random effect for the variance indicator was found, with a correlation between task easiness and the effect of r = -0.39, indicating that high variation of planning time is beneficial in difficult tasks while low variation is beneficial in easy tasks. → Eichmann 2019

q3 · i3 · associational · r2

GLMM analysis of log data from N = 1346 German students on 21 interactive PISA 2012 CPS tasks found no significant fixed effect for the variance indicator (estimate = -1.85, p = 0.155) but a significant random effect with correlation r = -0.39 with task easiness, indicating "in di fficult tasks a high variation of time is bene ficial while in easy tasks a low variation is bene ficial."

"The cor- relation between task easiness and the e ffect of the indicator was r = −0.39. The random e ffect indicates that in di fficult tasks a high variation of time is bene ficial while in easy tasks a low variation is bene ficial."
