Statistical Assesses
I computed preference having self-similarity because of the combining both bills in the pair of turns in order to create you to 8-part scale, in which the alternatives so much more with the self-dissimilar-transform are assigned to part step one, the choice maybe a whole lot more to your thinking-dissimilar-alter was allotted to point 4, the possibility possibly a lot more to the self-similar-change is allotted to point 5, and the alternatives a great deal more towards the thinking-similar-changes was assigned to area 8 (leftover choices was indeed tasked particular intermediate situations).

Recommendations (averaged for each rater) each and every feature (elegance inside enough time-title perspective, sincerity an such like.) were in addition opposed on one-shot t-evaluating from the expectations off cuatro.5 (haphazard choices) to check on the possibility aftereffect of self-similarity on each sort of score.
