This third edition aims to equip students with the skills to apply statistical analysis and quantitative techniques in research and the working environment where their knowledge can lead to effective decision-making. The book effectively combines theory and practice in providing: a theoretical framework for statistical problem-solving; a practical step-by-step approach to applying methods and calculations; a complete list of outcomes in each unit; worked examples with detailed explanations; and, practice in the form of guided activities and a range of self-test questions. The contents include the collection and presentation of data, descriptive measures, index numbers, regression and correlation analysis, time series, probability and probability distributions, statistical estimation and hypothesis testing. Calculation skills are revised in Part 2, a section that covers technology, elementary calculations, percentages and ratios, equations, graph construction and interest calculations. This edition includes examples and activities which cover not only the business field, but also food and biotechnology, engineering, medicine and environmental studies.
