Two applets are provided; one for testing the assumptions beneath two-sample hypothesis tests, and one for calculating the test statistic and p-value.Sun, 24 Feb 2013 10:52:30 -0500IDEAL: Hypothesis Testing for Paired Differences in Means
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1313
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1313This page provides three examples designed to illustrate hypothesis testing for paired differences in means. Example #2 requires Lisp-Stat. The other two examples each contain applets that calculate the test statistic and p-value. Examples #1 and #3 are about city murder rates and types of corn seed, respectively.Sun, 24 Feb 2013 10:49:49 -0500IDEAL: Hypothesis Testing

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2327
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2327Researchers and students alike often mistake any overlap among 95% confidence intervals to denote a statistically non-significant p value. However, confidence intervals can overlap and still correspond to a statistically significant p value for an independent sample t test. The confidence interval (CI) applet will help learners understand the relationship between confidence interval overlap and statistical significance.Sun, 1 Apr 2012 10:08:50 -0400Song: If Only P were greater

Lyrics written by Denise Tran, a student at University of Toronto, Mississauga in Fall 2010 as part of an assignment in a biometrics class taught by Helene Wagner. May be sung to the tune of the 2001 Grammy award winning song "Drops of Jupiter (Tell Me)" by the rock band Train (Patrick Monahan, Robert Hotchkiss, James Stafford, Scott Underwood, and Charlie Colin).

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2101
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2101June 22, 2010 Activity webinar presented by Paul Roback, St. Olaf College and hosted by Leigh Slauson, Capital University. This webinar describes an in-class activity, motivated by Case Study 1.1.1 in The Statistical Sleuth, in which students compose haiku poems about statistics. Their poems are used to introduce two-sample t-tests and randomization tests. In addition, the in-class experiment leads to good discussion about experimental design issues, where students compare our design to the actual experiment described in Amabile et al.(1985) "Motivation and Creativity: Effects of Motivational Orientation on Creative Writers", Journal of Personality and Social Psychology 48(2): 393-399. I use this activity on the first day of our second course in applied statistics (Statistical Modeling), but it could easily be used in an introductory course as well.Examples of haiku poems which have resulted from this activity can be found under CAUSEweb > Resources > Fun > Poem (direct link), or at www.causeweb.org/cwis/SPT--FullRecord.php?ResourceId=1883.Mon, 12 Jul 2010 05:00:44 -0400**Stat2Labs

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2047As mentioned on the home page of this resource "This site presents workbook-style, project-based material that emphasizes real world applications and conceptual understanding. This material is designed to give students a sense of the importance and allure of statistics early in their college career. By incorporating many of the successful reforms of the introductory statistics course into a wide range of more advanced topics we hope that students in any discipline can realize the intellectual content and broad applicability of statistics."Wed, 28 Apr 2010 11:29:41 -0400Student's T Tester Applet
