1. if i have 11 sets of data but only critical values for 10 and 12 sets of data would i use the critical value for 12 set of data to find out if i reject/accept the null?
2. I've moved this to the maths study help forum where hopefully you'll get more responses

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
5. 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.

7. 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.
