Data Presentation

  • A sketch by Anastasia Mandel reinterpreting "Red Square: Painterly Realism of a Peasant Woman in Two Dimensions" by Kazimir Severinovich Malevich (1915) with the statistical caption "R^2, or it might be a Russian square, used when there is a shortage of the Latin ones." This is part of a collection of sketches by Anastasia Mandel and their accompanying statistical captions written by Stan Lipovetsky and Igor Mandel that took first place in the cartoon & art category of the 2009 A-Mu-sing contest sponsored by CAUSE. The collection and their accompanying statistical captions discussed in the paper "How art helps to understand statistics" (Model Assisted Statistics and Applications, 2009) by Stan Lipovetsky and Igor Mandel in volume 4 pages 313-324. Free to use in classrooms and on course websites.

  • August 25, 2009 Activity webinar presented by Michelle Everson, University of Minnesota and hosted by Leigh Slauson, Capital University. In a classroom setting, students can engage in hands-on activities in order to better understand certain concepts and ideas. Replicating hands-on activities in an online environment, however, can be a challenge for instructors. The purpose of this webinar is to present an applet that was created to replicate a "Post-it Note" activity commonly used in classroom sections of an undergraduate introductory statistics course at University of Minnesota. The Post-it Note activity is meant to help students develop a more conceptual understanding of the mean and the median by moving a set of Post-it Notes along a number line. During the webinar, participants have an opportunity to see and experience just how online students are able to interact with an applet named the "Sticky Centers" applet, and the webinar presents the kinds of materials and assignments that have been created to use in conjunction with this applet. The webinar ends with a preview of a newer applet that is being developed in order to replicate the famous "Gummy Bears in Space" activity (presented in Schaeffer, Gnanadesikan, Watkins & Witmer, 1996). A supplemental student handout is available for download free of charge.

  • The same set of statistics can produce opposite conclusions at different levels of aggregation. is a quote useful in teaching about Simpson's Paradox from American Economist Thomas Sowell (1930 - ). The quote may be found on page 102 of his 1996 book "The vision of the Anointed: Self-Congratulation As a Basis for Social Policy". The quote may also be found at the science history website www.todayinsci.com.

  • Many of us, while teaching an introductory statistics course, have mentioned some of the history behind the methodology, perhaps just in passing. We might remark that an English chap by the name of R. A. Fisher is responsible for a great deal of the course content. We could further point out that the statistical techniques used in research today were developed within the last century, for the most part. At most, we might reveal the identity of the mysterious "Student" when introducing the t-test to our class. I propose that we do more of this. This webinar will highlight some opportunities to give brief history lessons while teaching an introductory statistics course.

  • A highly trained mathematical statistician without knowledge of the subject can be quite as dangerous as a subject-matter specialist trying to use statistical methods of which he has little knowledge. This is a quote of American Economist and Statistician Aryness Joy Wickens (1901 - 1991). The quote is from her Presidential Address to the American Statistical Association at the 112th annual meeting on December 28, 1952. The full address is reprinted in "JASA" v. 48 p. 1-14.

  • September 22, 2009 Activity Webinar presented by Diane Evans, Rose-Hulman Institute of Technology and hosted by Leigh Slauson, Capital University. This webinar is based on an activity found at www.lhs.logan.k12.ut.us/~jsmart/tank.htm and other on-line resources (see references). During World War II, the British and U.S. statisticians used estimation methods to deduce the productivity of Germany's armament factories using serial numbers found on captured equipment, such as tanks. The tanks were numbered in a manner similar to 1, 2, 3, ..., N, and the goal of the allies was to estimate the population maximum N from their collected sample of serial numbers. The purpose of this activity is to introduce students to the concept of an unbiased estimator of a population parameter. Students develop several estimators for the parameter N and compare them by running simulations in Minitab. Extra materials available for download free of charge.

  • A song parody by Steve Snodergren (a.k.a. Al G Bra: see www.reverbnation.com/algbra) that may be sung to the tune of "Superstition" by Stevie Wonder. Much of the song relates to concepts about summary statistics and taking a cautious approach to interpreting such summaries. This song appears on Al G Bra's "Old-Time Radical" CD.

  • It's Just STATA Code To Me is a song written by Dorry Segev of Johns Hopkins University that reflects on a number of issues in biostatistical data analysis. The song may be sung to the tune of Billy Joel's 1980 hit song "It's Still Rock and Roll To Me." The lyrics were written for Marie DIener-West's Biostatistics 653 course at Johns Hopkins that regularly asks students to create songs, videos, and poetry with biostatistics themes.
