marginally significantp = 0.07
There was a marginally significant difference between the two cohorts in the number of perspectives represented [ t (7.30) = 2.33, p = 0.07, two-tailed, adjusted for unequal variances], although a Levene's test showed that the first cohort signers were significantly more variable in their performance ( F = 13.75, p < 0.01).
