N2 - A recently published AM Last Page presents five common methodological pitfalls of experimental research in medical education. 1 In this Last Page, we present four statistical pitfalls and their more appropriate alternatives. Pitfalls are illustrated with a case of a fictitious researcher who conducts a study with elements that are common in many medical education experiments (Figure 1). assistant professor, Mariëtte H. van Loon, PhD, assistant professor, and Anique B.H. de Bruin, PhD, associate professor, Maastricht University References 1.

Leppink J, Paas F, Van Gog T, Van der Vleuten CPM, Van Merriënboer JJG. Effects of pairs of problems and examples on task performance and different types of cognitive load. Learn Instr. 2014;30:32–43. 3. Van Breukelen GJP. ANCOVA versus change from baseline has more power in randomized studies and more bias in nonrandomized studies.
