Sigma Stats Workbook 'AS 1.11 Bivariate Data’ is a write-on student resource covering the statistics students must understand to gain Achieved, Merit, or Excellence in the internally assessed Achievement Standard 1.11 – 'Investigate bivariate numerical data using the statistical enquiry cycle' (AS 91036).
In this workbook students will find clear explanations and detailed worked examples showing what is required at each step of the statistical enquiry cycle. At the end of the workbook there are two Achievement Standard Tests: statistical investigations where students collect their own bivariate data. 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 :
- Define the Problem
- Data Display
- Understanding and Using Technology
- Looking at the Scatter Plot
- Fitting a Trend Line
- Analysing Bivariate Data
- Forming a Conclusion
- Planning the Investigation
- Investigations with Given Data
- Achievement Standard Tests
The Sigma Workbook 'AS 1.11 Bivariate Data' 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 1.11.
Once completed, 'AS 1.11 Bivariate Data' provides a useful set of revision notes at assessment time. It can be kept as a reference book if students intend taking a Year 13 statistics courses.
