Subclaims¶

q3 i0 No significant difference between DD and controls was found in distance estimation (r = -0.069, p = 0.315), with Bayesian evidence favoring the null. → Vigna Giulia 2022

q3 · i0 · associational · r2

NADL Informal distance estimation subtest comparing DD and control participants: DD mean 0.67 (SD 0.48) versus 0.73 (SD 0.45) for controls, effect size "−0.069", p = 0.315, Bayes factor 4.165 indicating substantial evidence of H0. Equivalence was not formally tested beyond the Bayesian analysis.
