About this Book
Statistics is an important tool for collecting, analysing, interpreting and presenting numerical data. It is widely used in disciplines such as Economics, Management, Finance, Accounting, Sociology and other fields where data-based analysis and decision-making are required.
Statistical Analysis, Graphs and Diagrams by Drishti Publications has been developed to help BPSC aspirants understand statistical concepts in a clear and systematic manner. The book begins with the fundamentals of statistics and gradually progresses towards data organisation, presentation techniques and numerical measures.
The book explains how raw and unclassified data can be organised into meaningful groups and classes. Topics such as classification of data, variables, class intervals, class limits, frequency and frequency distribution help aspirants develop a strong foundation for further statistical analysis.
Special emphasis is given to the presentation of data. The book covers textual, tabular and diagrammatic presentation and explains how statistical information can be transformed into easily understandable formats. Graphical tools such as bar diagrams, pie diagrams, frequency diagrams and arithmetic line graphs are discussed with examples.
The section on Measures of Central Tendency covers important averages such as Arithmetic Mean, Median and Mode along with Geometric Mean and Harmonic Mean. Methods for calculating arithmetic mean for grouped and ungrouped data, including direct, assumed mean and step deviation methods, are also explained.
With its combination of conceptual explanations, numerical examples, previous years’ questions and practice-oriented content, the book can be used for concept building, answer preparation, revision and self-assessment for BPSC Mains and other competitive examinations.
