Although, like others in the series, most of the topics are well set out, this one fails to impress on account of its coverage of probability; explanations should be better. There is no attempt to prove the fundamental laws of probability, even though Venn Diagrams are included and worse still, there just aren't enough worked examples to drive home to the average student, what to do and why.
Understanding probability is crucial to any statistics module, therefore this book can not be recommended for someone who finds this topic difficult. On the plus side, it does offer good coverage of the Normal Distribution, but even here, extra information could've been included for completeness. The section covering use of the Binomial Distribution makes no attempt to explain how the formula is derived, even though most students capable of a high grade would find it straightforward.
Those relying solely on this as their course book, would probably fail to achieve an A-grade as a result. Under these circumstances, best avoided: get 'A Concise Course in A-Level Statistics' instead. You'll end up with a much better understanding of the topics and it will also cover virtually everything needed for S2 and beyond. The earlier versions are best value-for-money, but don't cover Box and Whisker or Stem-Leaf Plots. Fortunately this is something which most students have studied at GCSE-level, so it shouldn't be a problem.
On the plus side, it does contain useful diagrams and tips. Also, each chapter ends with an exercise of exam questions by the AQA-board, with details of the year set. For the tutor or teacher, the ability to print out exercises from the cd supplied is very useful.
