##### Description

The Sigma Statistics Workbook follows the sequence of the seven NCEA Achievement Standards for Level 3 Statistics. Each exercise links to a corresponding exercise in Sigma Statistics. This makes it easy to find revision or extra practice material that directly matches the work covered in class.

The workbook offers brief worked examples, content summaries and hundreds of carefully-graded ‘in context’ problems that help students to develop understanding and explain statistical concepts in plain language.

It features comprehensive ‘write-on’ coverage of the new statistical concepts introduced at secondary level – including bootstrapping to obtain informal confidence intervals, randomisation to assess the significance of sample results, and experimental design (treatment and response variables, allocation of treatments, factorial design, controls, blocking, confounding, and more) – as well as new tools for interpretation, such as main effects plots and interaction analysis.

There is also new material on deterministic versus probabilistic models, and expanded coverage of risk and relative risk.

The Sigma Statistics Workbook features a Student CD that can be used on computers at home or at school. The CD contains:

• all the worked examples in Sigma Statistics
• all the spreadsheets referred to in the main text and this workbook – data sets, simulations, and answers
• links to internet websites that illustrate statistical concepts
• a formula summary
• statistical probability tables.
