      Description

      If a student who submits a quiz fails to answer a calculated question, the Answered Correctly percentage statistics for that question are incorrect - it counts the non-answer among the incorrect answers.

      In the example pictured below, 4 students submitted a quiz, but one of them failed to answer the calculated questions. Consequently, where there are 3 responses, two of which are correct, the statistics show 50% Answered Correctly (i.e., 2/4 answers) instead of 66% correct. When there are 3 responses and two are incorrect, it shows 25% answered correctly (1/4 instead of 1/3)
