Putting it all together
You will be give a data set with quantitative and qualitative variables. Decide what are your two groups and what your comparative variable will be. You will then have to analyse the data and write a report  showing evidence of each component of the Statistical Cycle: Pose a Question, Plan, Display, Analysis, Conclusion. Review: Achievement Objectives Manipulating data in Excel notes Class notes Good practice data sets and material on http://www.mathsnz.com Excellence Exemplar (link to MathNZ) Google doc View  Download

What you need to do for Achieve, Merit, Excellence What is expected based on PPDAC cycle Example assessments on TKI (car crash & elite athletes) Exemplar, Elite Athletes, Car Crash Injury Practice:



Prior to the assessment you will be given information on the context. You should do some research into to context to gain prior understanding to help during the assessment and have material to discuss in your report. You will be able to bring this contextual research into the assessment.
1) Generic Assessment Instructions: (get familiar with these)Use the statistical enquiry cycle to conduct your investigation and to write a report describing the investigation. Familiarise yourself with the data set provided. This will include doing research to help you understand the variables and develop a purpose for the investigation. Identify the variables you wish to investigate, and establish a related investigative comparison question. Conduct your investigation and write a report containing: As you write your report, take care to link your discussion to the context and to support your statements by referring to statistical evidence. 
2) What is expected...(based on the PPDAC cycle)Report Writing 

(1) Pose a Question Purpose of Investigation. Variables Defined & Data Source. Comparative Investigative Question. 
Achieve Merit Excellence 
(2) Plan 
Using existing data sets & selecting groups and an applicable variable to compare. 
(3) Display Graphs (with labels) Summary (sample) Statistics 
Achieve Merit & Excellence 
(4) Analysis: Describing and Comparing Sample Distributions:

Discussion of Sample Distributions: Achieve Merit Excellence 
(5) Analysis: Sample Variability 
Achieve / Merit / Excellence 
(6) Analysis: Statistical inference 
Achieve Merit Excellence 
(5) Conclusion 
Achieve Merit Excellence 
Notes: For the assessment students will be provided with a data set containing multiple variables. Background information related to the data set will be provided. There should be sourcing of relevant contextual knowledge about the situation under investigation from places such as the internet, the school or local library, newspapers and magazines. These sources should be referenced in their report.
