Introduction: Eric Tassone writes: I [Tassone] had to Google “ Mary Rosh ” but remember that imbroglio now. Made my day, too. But really I wanted to write to ask you about something related to Bill James. I first encountered his works at age 13, when a baseball coach talked up his books and lent me one (that I fear I never returned). I then read his Abstracts from ’84 or ’85 until they went away, and then some of his other books in the ’90s. Anyway, my question is: Do you know if these works are available on a CD or DVD-ROM or the web something, like they do sometimes w/ collections like Mad Magazine or the New Yorker cartoons or whatever? Maybe through his website, to which I do not subscribe? (By the way, Google Books produces search results for the ’83-’87 editions, but at most just little clippings, not the full book or anything.) I wonder why we don’t see more of this, since the marginal cost of re-packaging and distributing already-created content for which there is at least some pent

Introduction: I stumbled across a chart that’s in my opinion the best way to express a comparison of quantities through time: It compares the new PC companies, such as Apple, to traditional PC companies like IBM and Compaq, but on the same scale. If you’d like to see how iPads and other novelties compare, see here . I’ve tried to use the same type of visualization in my old work on legal data visualization . It comes from a new market research firm Asymco that also produced a very clean income vs expenses visualization (click to enlarge): While the first figure is pure perfection, Tufte purists might find the second one too colorful. But to a busy person, color helps tell things apart: when I know that pink means interest, it takes a fraction of the second to assess the situation. We live in 2012, not in 1712 to have to think black and white. Finally, they have a few other interesting uses of interactive visualization, such as cellular-broadband infrastructure around

2 0.66081703 1907 andrew gelman stats-2013-06-20-Amazing retro gnu graphics!
Introduction: Bill Harris writes: Speaking of strange graphics, http://makingsense.facilitatedsystems.com/2007/03/making-musical-sense-by-email-part-2.html shows an example of text (gnuplot’s dumb terminal) graphics of data from MCSim (code and other material available from http://makingsense.facilitatedsystems.com/2007/03/making-musical-sense-by-email-table-of.html). At another extreme, slide 20 of https://docs.google.com/viewer?a=v&pid;=sites&srcid;=ZGVmYXVsdGRvbWFpbnx3c2hhcnJpczEzfGd4OjZkNGFjZWZhOTAyYTFkMDg shows a stereogram of more MCSim output (I was a bit more naive back then). I included the stereogram as a bit of humor just to show what could be done with J graphics. Surprisingly, one person in the audience focused intently on that slide and, after a moment, said “Got it!” We spoke afterwards, and it turned out that he was on the board or at least a volunteer at the Portland (OR) 3D Center of Art & Photography (http://www.3dcenterusa.com/index.html).

Introduction: Here and here , for example. I just hope they’re using our survey methods and aren’t trying to contact the zombies face-to-face!
Introduction: A few months ago we discussed Ron Unz’s claim that Jews are massively overrepresented in Ivy League college admissions, not just in comparison to the general population of college-age Americans, but even in comparison to other white kids with comparable academic ability and preparation. Most of Unz’s article concerns admissions of Asian-Americans, and he also has a proposal to admit certain students at random (see my discussion in the link above). In the present post, I concentrate on the statistics about Jewish students, because this is where I have learned that his statistics are particularly suspect, with various numbers being off by factors of 2 or 4 or more. Unz’s article was discussed, largely favorably, by academic bloggers Tyler Cowen , Steve Hsu , and . . . me! Hsu writes: “Don’t miss the statistical supplement.” But a lot of our trust in those statistics seems to be misplaced. Some people have sent me some information showing serious problems with Unz’s methods

Introduction: Yongtao Guan writes: I [Guan] recently began a collaboration with OpenIntro, a group of volunteers from around the country (Duke, Harvard, UCLA, and U.Miami) focused on contributing to improvements in introductory statistics education. They are an active group that has a lot of energy and neat ideas. On behalf of OpenIntro, I’d like to invite the students in your introductory statistics course to participate in a student project competition we are sponsoring this semester. Chris Barr (Assistant Professor at Harvard Biostatistics) and I are co-chairing the competition this Fall. We are hoping to highlight the excellent work that students do by hosting the two best projects from each class at OpenIntro.org and publishing the winners of a larger competition in a paperback volume with brief discussion about each project. Details of the competition can be found at openintro.org/stat/comp. We’ve tried to make the structure general so any class that already has a project integrated

Introduction: David Brooks writes : There’s an atmosphere of grand fragility hanging over America’s colleges. The grandeur comes from the surging application rates, the international renown, the fancy new dining and athletic facilities. The fragility comes from the fact that colleges are charging more money, but it’s not clear how much actual benefit they are providing. . . . This is an unstable situation. At some point, parents are going to decide that $160,000 is too high a price if all you get is an empty credential and a fancy car-window sticker. One part of the solution is found in three little words: value-added assessments. Colleges have to test more to find out how they’re doing. I agree with that last paragraph. Eric Loken and I said as much in the context of statistics teaching, but the principle of measuring outcomes makes sense more generally. (Issues of measurement and evaluation are particularly salient to statisticians, given that we strongly recommend formal quanti
