q3 i? Rotational path length showed no significant Block 1-to-Retention reduction at group level. → Yinqi Huang 2026

q3 · i? · causal · r1

Null paired comparison on rotational path length in the teleoperation training study: "non-signi ficant" with t(23) = 1.020, p = 0.320 and a printed d of 0.210. Equivalence was not tested; the authors interpret this as continued exploration of wrist angles.

"In contrast, rotational path length did not show a Block 1-to-Retention reduction at the group level (Fig.1b). The pairedt test comparison between Block 1 and Retention is non-signi ficant, pairedt test: t(23) = 1.020, p = 0.320; Cohen’s d = 0.210; mean percentage change (Retention vs. Block 1) = 10.2%."
