Assessment criteria: Please see the last page of this document.

Context

In Assessment 1, you were asked to select an Australian suburb of your choice and write a report to your financial institution justifying your intention to invest in your selected suburb based on a complete descriptive evaluation of the data. In Assessment 2, you are required to access the anonymised reports written by 2 of your classmates for Assessment 1, and critique the charts, tables, and figures within them that you believe to be a poor representation of the data.

Instructions

1. Work through the 3 reports (in total) and identify the charts, tables, and figures that you believe to be a poor representation of the data. Justify your answer.

Please note, you do NOT need to re-draw the charts, tables, and figures. The question is asking you to first identify characteristics of good charts, tables, and figures and then compare these with what was presented by your classmates in Assessment 1.

2. You believe that your suburb is the place to invest based on a comparison of the value of total buildings ($m).

a) Is there sufficient evidence of a significant difference in the mean value of total buildings between the suburbs analysed in all 3 reports? Describe the hypothesis and/or regression tests you will use for test.

b) Discuss the ethical issues you might encounter in your evaluation and explain possible ways of overcoming them.
