The University of Sydney Page 1 QBUS6860 Visual Data Analytics Weekly Assignment 8 Dr Demetris Christodoulou Discipline of Accounting MEAFA Research Group http://sydney.edu.au/business/research/meafa The University of Sydney Page 2 Weekly Assignment 8 o The Weekly Assignment 8 asks to investigate the changing relation over time between income per capita and life expectancy o Theory suggests that as income per capita for a country increases, there would be more investment in education, public health, technology and pro-social initiatives in that country, thus improving living conditions overall and life expectancy at birth o More specifically, the graph objective to be analysed is defined as: “The changing relation between GDP per capita and life expectancy from 1961 to 2017” Hint: think of GDP per capita as an explanatory variable that can help explain the variation in life expectancy The University of Sydney Page 3 Weekly Assignment 8 The data is available from the World Bank Open Data initiative. o The life expectancy at birth by jurisdiction is found here: https://data.worldbank.org/indicator/sp.dyn.le00.in o The GDP income per capita (in constant 2010 UDD) by jurisdiction is found here: https://data.worldbank.org/indicator/NY.GDP.PCAP.KD o These datasets contain jurisdiction-level observations for life expectancy and GDP per capita o From these links you can download the CSV or Excel files – look for these links: o You are required to manage the data to prepare it for analysis. You are also required to validate the data as in every assignment The University of Sydney Page 4 Weekly Assignment 8 o We do not know in advance the answer to the graph objective question and we must investigate the changing relation between the two variables using a visual mining approach. o Thus, you are required to use your knowledge from Week 9 to analyse the graph objective using appropriate visual mining methods. Hint: not all visual methods are useful for this assignment. o Do not use any transformations. The data must be analysed exactly as provided by the World Bank links in their nominal values The University of Sydney Page 5 Weekly Assignment 8 o You are required to produce data just one graph that will show the changing relation between the two variables over time. This data graph must qualify as a high-quality data graph as discussed in weeks 1-6. o The graph objective is multidimensional involving observations on jurisdictions, years, GDP per capita and life expectancy. It is up to you how to design the graph, but you may want to consider using interactive features or using the motion retinal variable o You are not required to do any particular research on this research question, but you may want to do so if it helps you understand the question better The University of Sydney Page 6 Weekly Assignment 8 o You will be evaluated on the quality of data management, data validation, and the quality of the data graph o You will be evaluated on the application of appropriate visual data mining methods o You need to submit the Tableau workbook (.twbx), a Word or PDF report, and the managed Excel or CSV dataset
