This book contains notes, questions and practice assessments for **1.3 “Interpret and apply mathematical and statistical information in context”**. This standard is externally assessed but is completed in school as a digital Common Assessment Activity and is worth 5 credits. This book predominantly focuses on the statistical aspect of this standard alongside some of the key mathematical skills that are likely to be useful.

Students are also able to and encouraged to use appropriate technology in their learning and assessment for this standard.

In this workbook students will find **clear explanations** and **detailed worked examples** showing the step-by-step processes that will be needed to solve each type of problem, these are followed by a large number of practice **exercises **and** problems **of increasing difficulty. At the end of the workbook there is are **Practice Investigations**. Candidates should use this to evaluate their strengths and weaknesses before the internal assessment.

**Defining Data**
**Data Display**
**Measures of Centre**
**Making Comparisons**
**Scatter Plots**
**Interpreting Data**

The Sigma Workbook **'****1.3 Interpret and apply mathematical and statistical information in context’**** **is best bought before the standard is taught at school and used throughout this time as a classroom and homework resource. Alternatively, the workbook would make an excellent independent study resource in the lead-up to the external assessment of Achievement Standard 1.3.

Once completed, **'****1.3 Interpret and apply mathematical and statistical information in context’ **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 mathematics course.
