Experiments and surveys are conducted by scientists in agriculture and food science as a part of their career. They require  appropriate statistical treatment to validate data draw meaningful conclusions. Statistical courses are formulated in  post graduate study programme to make them adept in Statistical Methods. The present work is outcome of several years of teaching and close collaboration with Students and research scientists in  different colleges and research institutes. The experience led to endeavor a presentation of pioneer works on statistical  methods, without elaborate theoretical background, a majority of which rests on mathematical proofs.  The organization of the book on the relevant headings are sure to benefit students in the faculties of agriculture, food  science and related subjects.
