# Multivariate Quantitative Relationships

• ### Cartoon: The Four-Caster

A cartoon to use in teaching about the dangers of extrapolation in the context of predicting the future. Cartoon by John Landers (www.landers.co.uk) based on an idea from Dennis Pearl (The Ohio State University). Free to use in the classroom and on course web sites.
• ### Joke: Sausage Correlation

A joke that might be used in discussing correlation - especially in health studies. The joke is adapted from a joke told by comedic magician Omar Covarrubias. The revised joke was written by Larry Lesser, University of Texas at El Paso, for use in the statistics classroom.
• ### Poem: Regression to the Mean

Regression to the Mean is a 2009 poem by Andrew Porter of Wirral, England. The poem can be used in teaching about regression to the mean and the regression fallacy. Free for use in non-profit educational settings. A video featuring the poem being read aloud is at https://www.youtube.com/watch?v=D66I36fksZA

• ### Be an Actuary

For anyone who wants to know more about what an actuary does or how to become an actuary (including a comprehensive list of colleges with actuarial programs), this is an excellent resource.

• ### Mathematical Fiction

This site is a collection of information about references to mathematics (and probability/statistics) in fiction. Users can see an entire list (sorted by author, title or publication date)and can browse through the database to find references by genre, topic, motif or medium.

• ### Introduction to Levels of Measurement Module

In this module, students can test their knowledge of levels of measurement by attempting to determine the the level of measurement of ten different variables. For each variable, a statement is also provided and students can indicate whether the statement about the variable is valid or invalid (given the way in which the variable was measured). There is also a brief "refresher" included here about levels of measurement.

• ### 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.

• ### Webinar: Class Experiment: Introduce t-tests and more, with haiku poems.

June 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.

• ### Webinar: Incorporating Computer Simulations and Visualizations into Your Teaching

January 12, 2010 T&L webinar presented by Marsha Lovett (Carnegie Mellon University) and hosted by Jackie Miller (The Ohio State University). In Statistics as in many disciplines, students need to learn about complex concepts and dynamically changing processes. How can instructors help their students begin to "see" these complex topics the way experts do, and are there tools that can help? In this webinar, I will review key findings on how computer visualizations and simulations can best support student learning and then take those findings to generate effective strategies for teaching with simulations and visualizations.

• ### Webinar: Using Chance to Engage AP High School and Undergraduate University Students in the Study of Statistics

March 9, 2010 T&L webinar presdented by Dalene Stagl (Duke University) and hosted by Jackie Miller (The Ohio State University). During the past 20 years, undergraduate education has shifted from student as passive recipient of information to student as active participant in the classroom. I wrote an article for Chance magazine's 20th anniversary issue titled, "Using Chance to Engage Undergraduates in the Study of Statistics." The article gave examples of activities inspired by Chance magazine articles from the last 20 years. This webinar will take articles from a recent issue of Chance and demonstrate the ease with which any issue can be used to develop class activities that are fun for high school students and undergraduates whether the course is a basic quantitative literacy course, an AP statistics course, an introductory course for non-statistics majors, or a core or elective course for the statistics major.
