Subclaims¶

q2 i? Descriptive comparison of expert shot groups showed kneeling on average produced worse performance than the prone position, with prone conditions homogeneous and kneeling heterogeneous. → Goldberg 2018

Goldberg, B., Amburn, C., Ragusa, C., & Chen, D. (2018). Modeling Expert Behavior in Support of an Adaptive Psychomotor Training Environment: a Marksmanship Use Case. Int J Artif Intell Educ 28:194–224. https://doi.org/10.1007/s40593-017-0155-y

q2 · i? · design · r2

Visual examination of descriptive statistics (mean, min, max shot group size per expert per condition, Fig. 3) across the four stance/gear conditions; the authors state "kneeling on average produces worse performance than the prone position". No inferential statistic is printed here.

"What is most noticeable is the variability in performance when comparing shots produced in the prone condition against those in the kneeling stance (namely, kneeling on average produces worse performance than the prone position)."
