... one of the main functions of an analogy or model is to suggest extensions of the theory by considering extensions of the analogy, since more is known about the analogy than is known about the subject matter of the theory itself. is a quote by English science philosopher Mary B. Hesse. The quote is found in her 1952 paper "Operational Definition and Analogy in Physical Theories" "British Journal for the Philosophy of Science" (1952).

...no good statistician existed unless he, or she, had been so involved in practical experimentation that they appreciated and understood the problems of the experimenter, the process worker, the farmer and the laboratory assistant. is a quote of British applied statistician Stella V. Cunliffe (1917 - 2012). The quote comes from her Presidential address on November 12, 1975 to the Royal Statistical Society (she was the first women to hold the position). The full presentation can be found in "JRSS series A" vol 139 p. 1-19 and contains many interesting examples from her years working at Guiness Brewery and for the government at the Home Office.

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.

Every careful measurement in science is always given with the probable error... every observer admits that he is likely wrong, and knows about how much wrong he is likely to be. This is a quote by Welsh Mathematician and philosopher Bertrand A.W. Russell (1872 - 1970). The quote may be found in his 1931 book "The Scientific Outlook" and is also found on the science history website www.todayinsci.com
