      (note the originally supplied quiz_with_attempts.mbz is buggy and that will be handled @ MDL-44018)

      Click on the statistics quiz report for the quiz you restored.

      Notice the select box right at the top of the report page labeled : "Calculate statistics from"

      1. If you select there to show the statistics for 'Highest graded attempt' then the limit of variants to display will not be exceeded and you will as the attached tiff screenshot "stats_with_variants_less_than_limit.tiff".

      2. If you select to show "all attempts" then you will see only stats for three variants shown - the variants with the max, median and min facility index see "variants_past_limit.tiff" (the simulate data includes more than one attempt for each user and the users are seeing different variants on subsequent attempts)

      The same quiz and attempt data can be used to test MDL-41758 also, so if you are going to test that commit then you might not want to delete this quiz yet.

      the max number of sub questions and variants combined shown in the report will be controlled by a constant that will default to 10.

      If more than that are found then we will show the stats for the question with the minimum, median and maximum facility index.

      In the downloaded spreadsheets all sub questions stats will be broken down and shown, within reason.
