• ### Quote: Shaw on Assumptions

Even trained statisticians often fail to appreciate the extent to which statistics are vitiated by the unrecorded assumptions of their interpreters is a quote by Irish playwright George Benard Shaw (1856 - 1950). The quote may be found in the author's preface to his 1906 play "The Doctor's Dilemma", that contains an essay on his views of statistics and quantitative literacy amongst the public.

• ### Song: A Sample that's Skewed

A song about examining the assumptions in statistical procedures especially dealing with skewed distributions. The lyrics were written by Robert Carver of Stonehill College and were awarded second place in the song category of the 2011 CAUSE A-Mu-sing competition. The song is a parody of the 1961 classic pop song "Runaround Sue" written by Ernie Maresca and Dion DiMucci and sung by Dion backed by the vocal group, The Del-Satins. Musical accompaniment realization and vocals are by Joshua Lintz from University of Texas at El Paso.

• ### Quote: Ford on chance

There is no such thing as no chance is a quote by American businessman and founder of the Ford Motor Company, Henry Ford (1863-1947). The quote is from a speech given to the 1930 class of students at Edison Laboratory in Menlo Park, New Jersey. It is referred to on page 14 of the 1930 book "American Florist".

• ### Quote: Cox on Nonstandard Problems

Most real life statistical problems have one or more nonstandard features. There are no routine statistical question; only questionable statistical routines. is a quote by British Statistician Sir David R. Cox (1924 - ). The quote may be found on page 240 in Christopher Chatfield's 1991 article "Avoiding Statistical Pitfalls" in "Statistical Science".
• ### Cartoon: Elevator in the Stat Building

• ### Quote: Friedman on Testing

The only relevant test of the validity of a hypothesis is comparison of prediction with experience. is a quote of American economist and statistician Milton Friedman (1912 - 2006). The quote can be found in the chapter "The methodology of positive economics" written by Dr. Friedman as an original article in his 1953 book "Essays in Positive Economics" containing a collection of his earlier articles.

• ### Quote: Adams on Assumptions

• ### Webinar: A Guitar Hero Based Project in Mathematical Statistics

May 25, 2010 Activity webinar presented by Ivan Ramler, St. Lawrence University and hosted by Leigh Slauson, Capital University. This webinar discusses an undergraduate Mathematical Statistics course project based on the popular video game Guitar Hero. The project included: 1) developing an estimator to address the research objective "Are notes missed at random?", 2) learning bootstrapping techniques and R programming skills to conduct hypothesis tests and 3) evaluating the quality of the estimator(s) under certain sets of scenarios.
