BIOSTATISTICS is based on our experience of teaching the students of Biostatistics, Biotechnology, Biology, Pharmacy, Medicine, Nursing, B.Com and Life Sciences courses. Biostatistics is the study of the application of statistical methodology to biological variations, correlation, regression, testing of hypothesis, testing of significance, non-parametric tests in biological measurements. It is also known as ‘Biometry’. This book has been written in clear, lucid manner to cover practical and applied aspects of Statistics. It will help the graduate and postgraduate students of Biological Sciences.

We are very thankful to the Management, Principal and my friends Dr. K.Chennakeshavalu, Professor, Dept. of Computer Science, K. Ramesh, Dept. of MCA, Intell Engineering College, Anantapur and K.Venkataswamy, Programmer, S.K. University, Anantapur.

Comments, criticism and suggestions from students as well as teachers will be highly ap-preciated.
