All too often Statistics courses assume a high degree of mathematical competence, and inevitably students and research workers from non-mathematical backgrounds struggle. But Statistics does not have to be learnt like this: you can get a long way by approaching it as a logical puzzle, and further still by converting difficult statistical problems into simpler problems of pattern recognition. Interactive graphs and 'datagames' (where you can manipulate the raw data whilst watching the patterns and results change) build up an intuitive understanding of how Statistics works. This may well be all you need - but if not, you will have a good basic commonsense grounding from which to approach those previously bewildering textbooks.
We recently asked users of the single-user edition of Statistics for the Terrified to let us know their experiences of the tutorial. Look at their responses.
