Graphical Excellence- Analyze
Graphical Excellence- Analyze. Edward Tufte, a former statistics professor at Princeton, has written a number of books on excellence in visually presenting quantitative information. (Tufte, Edward, (2001) “The Visual Display of Quantitative Information,” Graphics Press, LLC, Cheshire, Connecticut. It’s a great reference book.) Let’s look at Tufte’s principles of graphical excellence. Excellence in statistical graphics consists of the following:<br /> <br /> 1. Complex ideas communicated with clarity, precision, and efficiency. <br /> 2. A well designed presentation of interesting data – a matter of substance, statistics and design. <br /> 3. Gives the viewer the greatest number of ideas in the shortest time, the least ink in the smallest space. <br /> 4. Tell the truth about the data. <br /> <br /> With the advent of the web, there are also a whole new set of tools for representing data. Go to the Information is Beautiful website (www.informationisbeautiful.net) and choose one of his Visualizations and analyze it according to the Tufte’s principals of graphical excellence. Write one page. <br /> <br /> Find an interesting graph on the web and write a one page analysis regarding it’s substance or lack there of. Make sure you include the graph in your homework. Use Tufte’s Principles of Excellence to evaluate the graph. <br /> <br /> Create a histogram and a line graph using EXCEL. You’ll need to find at least two data sets – one for the histogram graph (cross-sectional) and one for the line graph (time series.) Use your imagination and find some “interesting” data.
