http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1884"I failed math twice, never fully grasping probability theory. I mean, first off, who cares if you pick a black ball or a white ball out of the bag? And second, if you're bent over about the color, don't leave it to chance. Look in the damn bag and pick the color you want." is a quote by the fictional bounty hunter Stephanie Plum; a character of American novelist Janet Evanovich (1943-). The quote is from the 2002 novel Hard Eight.Fri, 24 Jul 2009 10:13:15 -0400Cartoon: The Lottery

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1746
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1746In this hands-on activity, students count the number of chips in cookies in order to carry out an independent samples t-test to see if Chips Ahoy® cookies have a higher, lower, or different mean number of chips per cookie than a supermarket brand. First there is a class discussion that can include concepts about random samples, independence of samples, recently covered tests, comparing two parameters with null and alternative hypotheses, what it means to be a chip in a cookie, how to break up the cookies to count chips, and of course a class consensus on the hypotheses to be tested. Second the students count the number of chips in a one cookie from each brand, and report their observations to the instructor. Third, the instructor develops the independent sample t-test statistic. Fourth, the students carry out (individually or as a class) the hypothesis test, checking the assumptions on sample-size/population-shape.

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=391
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=391This applet is programmed to illustrate the code-breaking process using the Vigenere encryption as the code. The Vigenere encryption is broken by comparing histograms of various frequencies until the correct guess is obtained. A wrong guess for the period p leads to relatively flat histograms. The code breaker in this case repeats the analysis with a new trial period. Tue, 17 May 2005 05:29:14 -0400
