This book explores the diverse facets of mathematics and its bound less applications and cater to needs of students such as Agriculture, Horticulture, Agricultural Engineering, Fisheries Engineering and common Engineering. This book has been written to meet the requirements of graduate students of all Indian universities. As far as possible mathematical complexity has been avoided and wherever necessary, the notations and terminologies have been clearly described with detailed explanation of mathematical steps involved. It designed to be user-friendly. Each chapter of this book has complete theory and large number of solved problems. It has been made to make the language simple and easily understandable which conforms to definitions and explanations. The matter has been gradually developed in logical and methodical manner involving as little as possible. We are sure that it will be invaluable both to the students and the teacher alike

Measures of central tendency.

Mean, median, mode –types of mean- Ungrouped or Raw Data formula with simple problems- Grouped  data with simple problems(when class intervals not given, when class intervalsgiven)- problems for the mean of the given data by step deviation method-Combined mean- Weighted mean - Merits, Demerits and uses of Arithmetic Mean-Definition of median- ungrouped- grouped(When the series is discrete and continuous)- Merits and Demerits of median-Definition of mode- simple problems for grouped and ungrouped- Merits and Demerits of mode-definition of  Geometric Mean-problems for Discrete and continuous series- definition of Harmonic Mean with problems.
