Subclaims¶

q2 i? In the reanalysis of Aldekhyl et al. (2018) data, AIC preferred a quadratic and BIC a linear model for the mental effort–workload relation; the quadratic term was statistically significant at α = 0.05 but the evidence was not strong. → Jimmie Leppink & Patricia Pérez-Fuster 2019

q2 · i? · associational · r1

Reanalysis of repeated-measurement data (4 ultrasound scenarios per participant, 29 participants) from Aldekhyl et al. (2018); the criteria disagreed, and the quadratic term was significant: "F1, 106.565 = 4.142, p = 0.044, B = 0.576".

"The only study for which AIC and BIC indicate a different preference is Aldekhyl et al. (2018): AIC prefers Model 2 (quadratic: H 2) while BIC prefers Model 1 (linear: H 1). The difference in R2M between these two models is about 0.006 and the difference in df is 1. In Model 2, we find for the quadratic term: F1, 106.565 = 4.142, p = 0.044, B = 0.576, and 95% CI = [0.021; 1.131]."
