• Quote: Boole on Data

Do not make things easy for yourself by speaking or thinking of data as if they were different from what they are; and do not go off from facing data as they are, to amuse your imagination by wishing they were different from what they are. Such wishing is pure waste of nerve force, weakens your intellectual power, and gets you into habits of mental confusion. is a quote by English mathematician and mathematics educator Mary Everest Boole (1832-1916). The quote is found on page 7 of her 1909 book "Philosophy and Fun of Algebra", (C.W. Daniel, Ltd.) written to bring then modern mathematical ideas to children. The book is available online through Project Gutenberg at www.gutenberg.org/files/13447/13447-pdf.pdf

• Webinar: Mites and Wilt Disease - Using Simulation to Examine a 2 x 2 Table

January 26, 2010 webinar presented by Alicia Gram, Smith College, and hosted by Leigh Slauson, Capital University. This webinar describes an activity that uses data collected from an experiment looking at the relationship between two categorical variables: whether a cotton plant was exposed to spider mites; and did the plant contract Wilt disease? The activity uses randomization to explore whether there is a difference between the occurrence of the disease with and without the mites. The webinar includes a discussion of the learning goals of the activity, followed by an implementation of the activity then suggestions for assessment. The implementation first uses a physical simulation, then a simulation using technology. (Extra materials, including Fathom instructions for the simulation, available for download free of charge).
