q2 · i? · causal · r1

Online validation survey of teachers of the D/HH, ASL teachers, interpreters, and linguists (N = 30; n = 7-9 per video pair) judging video pairs; enjoyability similarly fit an equal-distribution model, and most participants (n = 19) found neither video frustrating.

"We then compared our results with a predicted model of an equal distribution for preferences for "CM,"" EM," and "both" with a limited number of responses for"neither" and found no significant difference between our data and this hypothesized model (X2(3) = 0.51,p = 0.918)."
