Preface to Second Edition
When I was following the present day syllabi of various universities
I found some units such as Multivariate Statistical Methods etc.,
are added compared to my first edition. I was considering to bring
second edition for a long time to update the Statistical Theory to
match the requirements of the courses.
In this edition a new Chapter on Multivariate Statistical Methods
is added which is useful to Postgraduate and Ph.D. students in
Agriculture Veterinary and Home sciences. Good number of examples
are added, besides practical applications. after each chapter of
Statistical Methods. wh}ch are useful to undergraduate and
postgraduate students.
This book also covers courses such as 'Data Analysis for
Managers taught to Agricu Itural Business Management PG students.
Quantitative methods and Analysis Techniques taught to B.Plan and
MURP students in JNTU and also courses on statistics taught to
Biotechnology PG students in Agricultural and other traditional
universities.
This book is also intended to serve as an effective reference
book to Research Workers in Agriculture, Veterinary and Home
Science faculties.
I am thankful to MIS Nikhil Shah and Anil Shah of
BS Publications, Hyderabad for taking initiative in bringing the second
edition of this book.
