q2 · i? · causal · r2

Descriptive analysis (Results §4.1) of the trustworthiness ratings on nine-point scales; "discernment score: M = 0.44, SD = 1.17" indicates a slight expert preference. No inferential test is reported for this contrast in the quoted text.

"Both videos featuring experts (M = 6.77, SD = 1.33) and laypersons (M = 6.33, SD = 1.27) are rather positively evaluated (i.e., above the median point), with a slight tendency to favor videos featuring experts (discernment score: M = 0.44, SD = 1.17)"
