Patrick from Woodbridge school sent in the following solution:

"I made frequency graphs of the data sets and I tried to find similar features.

1. A G K M have no odd numbers so they are very likely to be one set.



2. B I J O each have almost all the numbers centred in two peaks at around 7 and 13. 


3. D E L N have few early numbers or late numbers (they are all grouped around the middle)


4. C F H P have the same general shape - a rise up to 17 ish, then a very steep drop.
