Scientific research involves proper setting up of plan of work to suit the objectives of the experiment. Selection of experimental ubjects (animals), design of experiment on which the research data is collected, analyses and interpretation of the data so obtained have to be scientific and as per norms so that the results will not only be acceptable but also will be repeatable with known Confidence. Veterinary and Animal Science research workers may not have a background of Mathematics that is required to understand intricate details of statistics; especially as far as derivations of the formulae and understanding statistical notations etc. are concerned. This is further compounded by the fact that most of the books discuss examples from field other than Veterinary and animal Science. Ready to use computer software for statistical analyses of the data have only complicated the matter further; the results of te research work are obtained mechanically and the veterinary and animal science workers can hardly feel the data and, consequently, the results. The Author is of the firm opinion that there is a no substitute for actural analyses of data on a scientific calculator. Therefore, examples exclusively on Veterinary and Animals Science fields with calculations done only on scientific calculator (with statistics mode) are the unique features of the book. Further, some of the statistical procedures are employed more frequently in some of the veterinary science fields. Hence, they are separately dealt in chapter Statistics in Scientific Veterinary fields. In view of the above, this book helps Veterinary and Animal Science workers to plan, design, analyze and interpret data with more confidence.
