I used the ranges of each set of data, to work out which sets go together. Alison's temperatures were more likely to have a greater range, whereas Charlie's data, on the weights of teenagers, is unlikely to have a small range. Therefore, I concluded that A, D and E, which have the largest ranges, were the temperatures, while B, C and F were the teenager's weights.

As you can see on the graphs for the data sets, A, D and E's values varied much more than B, C and F's, suggesting that they are the temperatures, as they are likely to vary more than teenager's weights.
