Aimed specifically at the first exam in Statistics of the Royal Society of Arts, this text should also be suitable for GCSE courses both for classwork and individual study. It seeks to introduce the subject in a manner that presumes no previous knowledge, requires only basic arithmetic, and never brings in a statistical concept without prior explanation and preparation. Each chapter has a summary and a set of self-review questions intended to reinforce learning and inspire confidence. Further questions which test the deeper understanding of the material are also included, with answers provided at the back of the book. A lecturer's supplement is available.
