The revised edition of the book 'Fundamentals of Statistics' by S.C. Gupta was out in April 2004 Since then, a large number of teachers and students of Statistics from all over the country have been pressing us to bring out the revised edition of our boo 'Practical Statistics' which should provide solutions to most of the typical problems given in the Exercise Sets of the book 'Fundamentals of Statistics'. This book is the outcome of their valued suggestion and may be regarded as a supplement to the book 'Fundamentals of Statistics'. This book is a modest though determined, bid to serve as a self-study text-book, for B. Com. (Pass), B. Com. (Honours), B.A. (Economics Hons.), M. Com., M.A. (Economics), courses of Indian Universities and also for those preparing for Chartered Accountancy (C.A.), Cost and Works Accountancy (ICWA), and MBA Examinations. The stress is on the applications of techniques and methods most commonly used by statisticians. The lucidity of style and simplicity of expression have been the twin objectives in preparing this text. Wherever desirable, the notations and terminology have been clearly explained and then all mathematical steps have been explained in detail. A very large number (over 1,200) of typical problems mostly selected for C.A..; I.C.W.A. and various university examination papers have solved as illustrations so as to expose the students to different technique of tackling the problems ans enable them to have a better and thoughtful understanding of the basic concepts of the theory and its various applications. At many places explanatory remarks, working steps and alternative methods have been given to widen readers' horizon. Moreover in order to enable the readers to have a proper appreciation of the subject-matter and to fortify their confidence in the understanding and application of methods, a large number of carefully graded problems, mostly drawn from various university examination papers, have been given as Revisionary Exercise-Sets in each chapter. Answers to the problems in the exercise sets are given at the end of each problem independently and so, instil confidence in them. This book which contains 20 chapters, is primarily intended to serve as a self-helf or self-study text for the readers. Self-helf induces self-confidence which is a must for success in any discipline.
