Putting it all together
You will be given a data set with quantitative and qualitative variables. Spend time researching and making wise variable choices that will allow lots of quality discussion when you do your report. QUALITY not dribble. use the Assessment checklist (Class notes) How to reference research (link to magsmaths.com) Ensure you are familiar with Class Practice Assessment The investigation is to be written as a report including: 1. An Introduction: Aim, Research Question, Definition of variables etc. 2. Make Scatterplot’s to investigating any relationship. 3. Model (Linear) 4. Discussion 5. Conclusion

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. (get familiar with these) You have been given data from... Use the statistical enquiry cycle to carry out a statistical investigation to determine if there is a relationship between at least one pair of variables. 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.  Pose an appropriate relationship question that can be answered using variables in the data set. The variables you choose must be numerical, and the variable you use as your response variable must be continuous. You may choose to investigate more than one pair of variables. Select appropriate display(s) to graph your data.  Identify features in the data, including the nature and strength of the relationship.  Use your model to make prediction(s).  Write a conclusion answering your question.  Support your conclusion by referring to your analysis and/or features of the visual display(s). Include a reflection on your process, which could consider other relevant variables, or evaluate the adequacy of your model(s). In writing your report, link your discussion to the context and support the statements you make by referring to statistical evidence.
