I am currently doing my statistics GCSE and I have to do a spearmans rank. So if i do scatter diagram of boys and girls showing their age and how long they took to do a literacy and maths puzzle, would my 2 sets of data (in order to work out) spearmans rank be the two puzzles or the puzzles and age knowing that it has to match my hypothesis: THe older the student, the quicker it takes to do the test.
