Description: ENDORSED BY CAMBRIDGE INTERNATIONAL EXAMINATION This book is one of a series which has been especially written for the University of Cambridge International Examinations syllabus for International AS and A Level Mathematics (9709). Together the books cover all the modules and give full coverage of the Mathematics syllabus. There are clear explanations and worked examples for each new topic. The activities, investigations and graded exercises provide plenty of practice. Statistics covers the requirements of Sl and S2. Sl includes representation and interpretation of data, probability, discrete random variables, permutations and combinations, the binomial distribution and the normal distribution. S2 covers hypothesis testing, the Poisson distribution, continuous random variables, linear combinations of random variables, sampling and estimation. There is a disc included with each book. The discs contain Test Yourself interactive multiple-choice questions, and Personal Tutor audio-visual step-by-step worked examples of exam-style questions to support Sl. The authors are experienced examiners and teachers who have written extensively at this level. ? Endorsed by University of Cambridge International Examinations for this syllabus ?

This brand new series has been written for the University of Cambridge International Examinations course for AS and A Level Mathematics (9709). This title covers the requirements of S1 and S2. The authors are experienced examiners and teachers who have written extensively at this level, so have ensured all mathematical concepts are explained using language and terminology that is appropriate for students across the world. Students are provded with clear and detailed worked examples and questions from Cambridge International past papers, so they have the opportunity for plenty of essential exam practice. Each book contains a free CD-ROM which features the unique 'Personal Tutor' and 'Test Yourself' digital resources that will help students revise and reinforce concepts away from the classroom: - With Personal Tutor each student has access to audio-visual, step-by-step support through exam-style questions - The Test Yourself interactive multiple choice questions identify weaknesses and point students in the right direction
