The revised edition of the book “Fundamentals of Statistics” by S.C. Gupta was out in January 2012. 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 book ‘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 of the book ‘Fundamentals of Statistics.’
This book is 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. (Economic), course of Indian Universities and also for those preparing for Chartered Accountancy (CA), 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 objective in preparing this text. Wherever desirable, the notations and terminology have been clearly explained and then al mathematical steps have been explained in detail.
A very large number (over 1.200) of typical problems mostly selected from CA;ICWA and various university examination papers have been solved as illustrations so as to expose the students to different techniques of tacking the problems and enable them to have a better and thoughtful understanding of the basic concepts of the theory and its various applications. At many place, explanatory remarks, working steps and alternative methods have been given to widen readers’ horizon. Moreover, in order to enable the reader 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 paper 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 All these are bound to motivate and stimulate the reader to work out the given problems independently and so, instill confident in them. This book which contains 20 chapter, is primarily intended to serve a self-study text for the readers Self-help induces self-confidence which is a must for success in any discipline.
