      Description

      The help file grade/aggregation.html states:

      "Median of grades - The middle grade (or the mean of the two middle grades) when grades are arranged in order of size..."
      Bellow there is an example of such calculation:

      A1 70/100, A2 20/80, A3 10/10, category max 100:
      0.7 + 0.25 + 1.0 --> 0.25 --> 25/100

      IMHO the median of these three should be 0.7 -> 70/100 and not 0.25 -> 25/100 as stated. It is quite confusing...

        Please note, the help file should be fixed at other places as well, e.g.

        min(0.7 + 0.25 + 1.0)
        should read
        min(0.7 ; 0.25 ; 1.0)

        max(0.7 + 0.25 + 1.0)
        should be
        max(0.7 ; 0.25 ; 1.0)

        +1 for this one, I think David is right. Helen could you fix this real quick? If you don't mind I could fix it and commit it too. Thanks!

        OK as I recall Helen might be on vacation right now, so I went ahead and committed the change (Helen I hope that you don't mind). File is located in /lang/en_utf8/help/grade/aggregation.html, revision 1.1.2.6. I'm closing this ticket now unless that other issues are found then we could reopen it. Thanks!

        Final commit revision 1.1.2.7 - some minor formatting changes to make the content more consistent and readable. Committed to 1.9 stable and head. Ticket closed.
