Sigma Stats Workbook **'AS 1.13 Elements of Chance'** is a write-on student resource covering the statistics students must understand to gain *Achieved*, *Merit*, or *Excellence* in the internally assessed Achievement Standard 1.13 – *'Investigate a situation involving elements of chance'* (AS 91038).

In this workbook students will find **clear explanations** and **detailed worked examples** showing what is required at each step in an investigation involving experimental probability. At the end of the workbook there is an Achievement Standard Test: An investigation involving elements of chance. Candidates should use this to evaluate their strengths and weaknesses before the internal assessment.

A full set of **answers** is included, which acts as a guide to structuring quality answers. An abbreviated version of the Achievement Criteria and Explanatory Notes of the Achievement Standard itself complete the resource.

**Topics Covered in this Workbook Include** :

**Probability from Experiments****Organising the Data****Data Display****Using Technology****Theoretical Probability****Expectation****Define the Experimental Problem****Plan the Experiment****Display the Experimental Data****Discuss the Experimental Data****Theoretical Comparisons****Form a Conclusion****Practice Investigations****Achievement Standard Test**

The Sigma Stats Workbook **'AS 1.13 Elements of Chance'** is best bought before the standard is taught at school and used throughout the topic as a classroom and homework resource. Alternatively, the workbook would make an excellent independent study resource in the lead-up to the internal assessment of Achievement Standard 1.13.

Once completed, **'AS 1.13 Elements of Chance'** provides a useful set of revision notes at assessment time. It can be kept as a reference book if students intend taking a Year 12 statistical course.
