# E Qualitative item characteristics

Item reading level information was performed via the packages quanteda version 2.1.2 and quanteda.textstats version 0.94.1 in R version 4.0.5 (2021-03-31) . Two indices were investigated: “Flesch-Kincaid” is the same grade level index that’s currently used by Microsoft Word whereas “Dale.Chall” reflects Nwd [“difficulty” of words; ]. These indices are primarily influenced by two qualitative characteristics: Nwf, which is the number of words matching the Dale-Chall List of 3000 “familiar words,” and Nwd, which is the number of “difficult” words not matching the Dale-Chall list of “familiar” words.

The average Flesch-Kincaied (e.g., reading grade) for our 36 candidate pilot items was 6.2 (sd = 3.04). The average Dale-Chall index was 38.61 (sd = 11.11).
