dap1.tex Biostat 230 Statistical Graphics 1 Data Analysis Project 1: Olympic Medal Counts Goal: Graphically analyze the Olympic Medal Count data as a function of population and Gross Domestic Product (GDP). The data is in the ﬁle olympicmedals2008.txt, the ﬁrst line is a header line. Medal count data came from yahoo sports, and the populations and Gross Domestic Product (GDP) come via Wikipedia, from the CIA World Fact Book. GDP is in millions of US dollars, year 2007. Population is in millions of people. Your goals are to graphically (1) describe the medal counts as functions of population and GDP and to identify (2) which countries did best given their population and GDP. Some things to think about: (1) You will need to reexpress your data. Explain how you do it and why. (2) Is there missing data? Your report should be a maximum of approximately 1.5 pages, typed, double-spaced. You may include a FEW plots or tables (I suggest 2-4 max) in an appendix. The report should be written as a report, not as answers to a series of questions. You must refer to any tables or plots in the main text. All plots and tables must be carefully labeled, captioned and described. Plots should be drawn in R. Plot and table quality and relevance will contribute to the overall grade. You should describe what analyses/plots/tables/summaries you looked at and your conclusions. Con- clusions should be justiﬁed using tables and plots so that the conclusions become believable.
