q3 i3 Confidence correlated with final diagnostic accuracy (r = 0.51) but not with the first hypothesis (r = 0.232). → Lajoie 2001

Evidence¶

Lajoie 2001¶

Lajoie, S. P., Lavigne, N. C., Guerrera, C., & Munsie, S. D. (2001). Constructing knowledge in the context of BioWorld. Instructional Science, 29(2), 155-186. http://www.jstor.org/stable/41953546

q3 · i3 · associational · r1

Correlational analysis of BioWorld computer-trace data from the 20 groups: final confidence related to diagnostic accuracy (r = 0.51, p = 0.022) while initial confidence did not (r = 0.232, p = 0.325). The authors state that as accuracy increased, confidence increased.

"Furthermore, confidence was tied to final diagnostic accuracy (r = 0.5 1 , p = 0.022) but not to first hypothesis (r = 0.232, p = 0.325)."
