* Percentages may not sum to 100 due to rounding. † Two-sided Wilcoxon signed ranks test. ‡ A properly specified question was one that had an explicit statement for each of the four dimensions of question specificity. If a question had at least one dimension coded as absent, it was classified as mis-specified.
