Available in PDF, EPUB and Kindle. Book excerpt: This book is written for MBA students and statistics teachers of Anna University affiliated institutions. It is a natural outcome of the author, after teaching statistics several times for MBA students. It is shaped and reshaped several times to heal the heart and soul of non-mathematical community. This book covers all models in all chapters, completely. Problem identification is the most difficult task in statistics for the students. Hence a new approach with short cuts is used throughout the book to simplify this task. This book differs from other books in approaching the sampling distribution. Sampling distribution chapter is usually classified based on standard error, confidence interval estimation and hypothesis testing; or based on the number of sample sets – one sample, two sample; or based on the sample size – large sample, small sample; or based on the statistical tables – such as z test, t test, chi square test and F test. But this book classifies the sampling distribution chapter based on the parameters – Mean, Proportion, Standard deviation cum Variance. Because the very first thing to be decided by any researcher or a practitioner or a decision maker before applying any statistical tool is the parameter to be used and none other! The syllabus is reorganized as per the convenience of the students. 2nd and 3rd unit of the syllabus is reorganized based on the parameters – Mean, Proportion and Standard deviation instead of standard error, interval estimation and hypothesis testing. Similarly the discrete distributions – binomial & Poisson distributions and Probability rules of 1st unit are dealt at the end. Probability rules are grouped based on two models – associated events and successive events. Each Chapter contains illustrations, examples, formula, short answers and exercise.
