Description
From OU spec : "Positions or items that appear to be performing particularly badly (Discrimination coefficient below XXX? perhaps other conditions too?) should be highlighted. We don't yet have a clear picture what constitutes 'particularly badly', so structure the code so that it is clear which part you need to tweak to change this. For example, have a function is_dubious_question($row_of_data). "
There is a function is_dubious_question on the statistics table passed all the stats for that question and other question data and that returns a bool.
Here is a patch (dubious.txt) that almost applies cleanly to the OU codebase. The theme changes may have to be applied by hand.
