Introduction: By now you all must be tired of my one-sided presentations of the differences between infovis and statgraphics (for example, this article with Antony Unwin). Today is something different. Courtesy of Martin Theus, editor of the Statistical Computing and Graphics Newsletter, we have two short articles offering competing perspectives: Robert Kosara writes from an Infovis view: Information visualization is a field that has had trouble defining its boundaries, and that consequently is often misunderstood. It doesn’t help that InfoVis, as it is also known, produces pretty pictures that people like to look at and link to or send around. But InfoVis is more than pretty pictures, and it is more than statistical graphics. The key to understanding InfoVis is to ignore the images for a moment and focus on the part that is often lost: interaction. When we use visualization tools, we don’t just create one image or one kind of visualization. In fact, most people would argue that there is

2 0.30994016 847 andrew gelman stats-2011-08-10-Using a “pure infographic” to explore differences between information visualization and statistical graphics

Introduction: Our discussion on data visualization continues. One one side are three statisticians–Antony Unwin, Kaiser Fung, and myself. We have been writing about the different goals served by information visualization and statistical graphics. On the other side are graphics experts (sorry for the imprecision, I don’t know exactly what these people do in their day jobs or how they are trained, and I don’t want to mislabel them) such as Robert Kosara and Jen Lowe , who seem a bit annoyed at how my colleagues and myself seem to follow the Tufte strategy of criticizing what we don’t understand. And on the third side are many (most?) academic statisticians, econometricians, etc., who don’t understand or respect graphs and seem to think of visualization as a toy that is unrelated to serious science or statistics. I’m not so interested in the third group right now–I tried to communicate with them in my big articles from 2003 and 2004 )–but I am concerned that our dialogue with the graphic

Introduction: To continue our discussion from last week , consider three positions regarding the display of information: (a) The traditional tabular approach. This is how most statisticians, econometricians, political scientists, sociologists, etc., seem to operate. They understand the appeal of a pretty graph, and they’re willing to plot some data as part of an exploratory data analysis, but they see their serious research as leading to numerical estimates, p-values, tables of numbers. These people might use a graph to illustrate their points but they don’t see them as necessary in their research. (b) Statistical graphics as performed by Howard Wainer, Bill Cleveland, Dianne Cook, etc. They–we–see graphics as central to the process of statistical modeling and data analysis and are interested in graphs (static and dynamic) that display every data point as transparently as possible. (c) Information visualization or infographics, as performed by graphics designers and statisticians who are

4 0.28065053 1584 andrew gelman stats-2012-11-19-Tradeoffs in information graphics

Introduction: The visual display of quantitative information (to use Edward Tufte’s wonderful term) is a diverse field or set of fields, and its practitioners have different goals. The goals of software designers, applied statisticians, biologists, graphic designers, and journalists (to list just a few of the important creators of data graphics) often overlap—but not completely. One of our aims in writing our article [on Infovis and Statistical Graphics] was to emphasize the diversity of graphical goals, as it seems to us that even experts tend to consider one aspect of a graph and not others. Our main practical suggestion was that, in the internet age, we should not have to choose between attractive graphs and informational graphs: it should be possible to display both, via interactive displays. But to follow this suggestion, one must first accept that not every beautiful graph is informative, and not every informative graph is beautiful. . . . Yes, it can sometimes be possible for a graph to

5 0.27461365 878 andrew gelman stats-2011-08-29-Infovis, infographics, and data visualization: Where I’m coming from, and where I’d like to go

Introduction: I continue to struggle to convey my thoughts on statistical graphics so I’ll try another approach, this time giving my own story. For newcomers to this discussion: the background is that Antony Unwin and I wrote an article on the different goals embodied in information visualization and statistical graphics, but I have difficulty communicating on this point with the infovis people. Maybe if I tell my own story, and then they tell their stories, this will point a way forward to a more constructive discussion. So here goes. I majored in physics in college and I worked in a couple of research labs during the summer. Physicists graph everything. I did most of my plotting on graph paper–this continued through my second year of grad school–and became expert at putting points at 1/5, 2/5, 3/5, and 4/5 between the x and y grid lines. In grad school in statistics, I continued my physics habits and graphed everything I could. I did notice, though, that the faculty and the other

3 0.89149457 1604 andrew gelman stats-2012-12-04-An epithet I can live with

Introduction: Here . Indeed, I’d much rather be a legend than a myth. I just want to clarify one thing. Walter Hickey writes: [Antony Unwin and Andrew Gelman] collaborated on this presentation where they take a hard look at what’s wrong with the recent trends of data visualization and infographics. The takeaway is that while there have been great leaps in visualization technology, some of the visualizations that have garnered the highest praises have actually been lacking in a number of key areas. Specifically, the pair does a takedown of the top visualizations of 2008 as decided by the popular statistics blog Flowing Data. This is a fair summary, but I want to emphasize that, although our dislike of some award-winning visualizations is central to our argument, it is only the first part of our story. As Antony and I worked more on our paper, and especially after seeing the discussions by Robert Kosara, Stephen Few, Hadley Wickham, and Paul Murrell (all to appear in Journal of Computati

Introduction: Infovis and Statistical Graphics: Different Goals, Different Looks (and here’s the article) Speaker: Andrew Gelman, Columbia University Date: Thursday, November 29 2012 Time: 4:00PM to 5:00PM Location: 32-D463 (Star Conference Room) Host: Polina Golland, CSAIL Contact: Polina Golland, 6172538005, polina@csail.mit.edu The importance of graphical displays in statistical practice has been recognized sporadically in the statistical literature over the past century, with wider awareness following Tukey’s Exploratory Data Analysis (1977) and Tufte’s books in the succeeding decades. But statistical graphics still occupies an awkward in-between position: Within statistics, exploratory and graphical methods represent a minor subfield and are not well-integrated with larger themes of modeling and inference. Outside of statistics, infographics (also called information visualization or Infovis) is huge, but their purveyors and enthusiasts appear largely to be uninterested in statisti

2 0.94233215 1044 andrew gelman stats-2011-12-06-The K Foundation burns Cosma’s turkey

Introduction: Shalizi delivers a slow, drawn-out illustration of the point that economic efficiency is all about who’s got the $, which isn’t always related to what we would usually call “efficiency” in other settings. (His point is related to my argument that the phrase “willingness to pay” should generally be replaced by “ability to pay.”) The basic story is simple: Good guy needs a turkey, bad guy wants a turkey. Bad guy is willing and able to pay more for the turkey than good guy can afford, hence good guy starves to death. The counterargument is that a market in turkeys will motivate producers to breed more turkeys, ultimately saturating the bad guys’ desires and leaving surplus turkeys for the good guys at a reasonable price. I’m sure there’s a counter-counterargument too, but I don’t want to go there. But what really amused me about Cosma’s essay was how he scrambled the usual cultural/political associations. (I assume he did this on purpose.) In the standard version of t

3 0.92178959 1485 andrew gelman stats-2012-09-06-One reason New York isn’t as rich as it used to be: Redistribution of federal tax money to other states

Introduction: Uberbloggers Andrew Sullivan and Matthew Yglesias were kind enough to link to my five-year-old post with graphs from Red State Blue State on time trends of average income by state. Here are the graphs : Yglesias’s take-home point: There isn’t that much change over time in states’ economic well-being. All things considered the best predictor of how rich a state was in 2000 was simply how rich it was in 1929…. Massachusetts and Connecticut have always been rich and Arkansas and Mississippi have always been poor. I’d like to point to a different feature of the graphs, which is that, although the rankings of the states haven’t changed much (as can be seen from the “2000 compared to 1929″ scale), the relative values of the incomes have converged quite a bit—at least, they converged from about 1930 to 1980 before hitting some level of stability. And the rankings have changed a bit. My impression (without checking the numbers) is that New York and Connecticut were

4 0.91947901 1101 andrew gelman stats-2012-01-05-What are the standards for reliability in experimental psychology?

Introduction: An experimental psychologist was wondering about the standards in that field for “acceptable reliability” (when looking at inter-rater reliability in coding data). He wondered, for example, if some variation on signal detectability theory might be applied to adjust for inter-rater differences in criteria for saying some code is present. What about Cohen’s kappa? The psychologist wrote: Cohen’s kappa does adjust for “guessing,” but its assumptions are not well motivated, perhaps not any more than adjustments for guessing versus the application of signal detectability theory where that can be applied. But one can’t do a straightforward application of signal detectability theory for reliability in that you don’t know whether the signal is present or not. I think measurement issues are important but I don’t have enough experience in this area to answer the question without knowing more about the problem that this researcher is working on. I’m posting it here because I imagine t

Introduction: I just read this article on the treatment of medical volunteers, written by doctor and bioethicist Carl Ellliott. As a statistician who has done a small amount of consulting for pharmaceutical companies, I have a slightly different perspective. As a doctor, Elliott focuses on individual patients, whereas, as a statistician, I’ve been trained to focus on the goal of accurately estimate treatment effects. I’ll go through Elliott’s article and give my reactions. Elliott: In Miami, investigative reporters for Bloomberg Markets magazine discovered that a contract research organisation called SFBC International was testing drugs on undocumented immigrants in a rundown motel; since that report, the motel has been demolished for fire and safety violations. . . . SFBC had recently been named one of the best small businesses in America by Forbes magazine.
