This book is part of the Cambridge Advanced Level Mathematics series, written specifically for the OCR modular mathematics syllabus. Each book or half-book corresponds exactly to one module. Statistics 1 has chapters on data representation, probability, expectation and variance, and the binomial distribution. It also introduces correlation and regression. Each chapter starts with a short list of learning objectives, and mathematical ideas are explained carefully and clearly, with many worked examples. There are plenty of exercises throughout, along with revision exercises and mock exam papers - all written by experienced examiners.
