Basic Statistics (Ninth Edition) is a trusted and widely adopted textbook designed to introduce students to the essential concepts and methods of statistics in a clear, accessible manner. Originally written for students in the biological, social, and behavioral sciences, the book has over time become a valuable resource for commerce students, higher secondary learners, and anyone seeking a non-technical understanding of statistical ideas. This thoroughly revised edition presents a well-structured progression of topics, beginning with the fundamentals of data, classification, and descriptive statistics, and gradually advancing to probability, theoretical distributions, correlation, regression, sampling, and statistical inference. Real-world applications in areas such as time series analysis, quality control, index numbers, and vital statistics make the content relevant and practical. Key additions in this edition include new sections on distribution fitting, updated sampling techniques, and enhanced mathematical appendices. The book also features five appendices covering essential background in mathematics, set theory, interpolation methods, number representation, and statistical tables. Each chapter includes a comprehensive set of exercises-ranging from multiple-choice questions to numerical problems and essay-style questions-along with selected solved questions from previous examinations. With its balanced emphasis on conceptual understanding and practical application, Basic Statistics remains an ideal companion for students at the undergraduate level and beyond. It is also a helpful guide for professionals, teachers, and general readers looking to gain a strong foundation in statistics without requiring a deep mathematical background.
