    That's strange. If that continues, you should report it to the developers on TSR in this forum here: http://www.thestudentroom.co.uk/forumdisplay.php?f=357

    If this problem continues and the staff don't respond, just make a thread in A-levels and quote me or another mod in to move it for you

    you take one category away (before ranking, from the set of 11 results, take 1 away, to have 10), the worst one or just the oddest one. And use the crit value for 10.

    The data mostly follows a trend (some values give repeat results) would getting rid of one of these be ok? It's results form a biology practical not that that makes any difference.

    From looking at past mark schemes, you can calculate it using either 10 pairs or 11 pairs of critical values. I would assume with the 11 pairs you would find a value half way between 10 pairs and 12 pairs but I would use 10 pairs of values just to be safe.
