Conditional Probability

  • "The Law of Statistics" is a poem by Scottish poet Eveline Pye from Glasgow Caledonin University. The poem was originally published in the February 2016 issue of Talking Writing magazine. "The Law of Statistics" is about the case of Sally Clark, who was wrongly convicted in England of killing two of her children based on an error in "expert" testimony regarding the probability of two crib deaths in the same family. The poem might be used in course discussions about conditional probability and Bayes Theorem.

  • 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).

  • Most accidents in well-designed systems involve two or more events of low probability occurring in the worst possible combination. is a quote by American systems engineering expert Robert E. Machol (1917 - 1998). The quote is found in his 1975 column "Principles of Operations Research" for the journal "Interfaces" vol. 5, pages 53-54 (this column was titled "The Titanic Coincidence."
