This book contains notes, questions and practice investigations for the different types of investigation for 1.1 “Explore data using a Statistical Enquiry Process. The four options for the assessment of this standard are: Comparison Investigation (Multivariate Data), Relationship Investigation (Bivariate Data), Time Series Investigation and Experimental Probability Investigation. One of these investigations only needs to be submitted to achieve the standard. This standard is internally assessed and is worth 5 credits. Students are also able to and encouraged to use appropriate technology, such as graphing calculators/software in their learning and assessment for this standard. Instructions in this book relate to the Casio fx-9750 and fx-9860 GIII.
Also in this book are notes and questions relevant to the Statistical Literacy component of 1.3 “Interpret and apply mathematical and statistical information in context”. This standard is externally assessed via a digital Common Assessment Activity and is worth 5 credits.
In this workbook students will find clear explanations and detailed worked examples showing what is required at each step of the mathematical methods cycle. At the end of the workbook there are Practice Exam Questions.
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 :
- Statistical Investigations
- Comparison Investigation
- Relationship Investigation
- Time Series Investigation
- Experimental Probability Investigation
- Statistical Literacy
- Practice Investigations / Papers
The Sigma Workbook 'Focus on Statistics' is best bought before the standards are taught at school and used throughout the topics 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 Standards 1.1 and 1.3.
Once completed, 'Focus on Statistics' 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.
