# Design of Experiments

• ### Quote: Kapitsa on Experiments

Theory is a good thing, but a good experiment is forever. is a quote by Russian nobel prize winning physicist Pyotr Leonidovich Kapitsa (1894 - 1984). The quote is found on page 160 of "Experiment, theory, practice, articles and addresses volume 46."

• ### Quote: Stewart on Theory and Experiment

...experiment without mathematics will neither sufficiently discipline the mind or sufficiently extend our knowledge... is a quote by Scottish geophysicist Balfour Stewart (1828 - 1887). The quote is found in a letter from Stewart to Henry Roscoe of Owens College on June 2, 1870.

• ### Webinar: This Little Piggy Teaches Probability

November 23, 2010 Activity Webinar presented by Stacey Hancock, Reed College, Jennifer Noll, Portland State University, Sean Simpson, Westchester Community College, and Aaron Weinberg, Ithaca College, and hosted by Leigh Slauson, Capital University. Extra materials available for download free of charge. Many instructors ask students to demonstrate the frequentist notion of probability using a simulation early in an intro stats course. Typically, the simulation involves dice or coins, which give equal (and known) probabilities. How about a simulation involving an unknown probability? This webinar discusses an experiment involving rolling (unbalanced) pigs. Since the probabilities are not equal, this experiment also allows the instructor to have students think about the concept of fairness within games.

• ### Webinar: Supporting Statistical Thinking Through a Capstone Project

July 27, 2010 Activity Webinar presented by Herle McGowan, North Carolina State University and hosted by Leigh Slauson, Capital University. Extra materials available for download free of charge. In this webinar, the webinar discusses the end-of-semester project that is used in North Carolina State's introductory statistics course. This project supports statistical thinking by allowing students to apply knowledge accumulated throughout the semester. Students are presented with a research question and must design and carry out an experiment, analyze the resulting data and form a conclusion over the course of several class periods.
• ### Cartoon: Placebo Tea

A cartoon for use in discussions about the value of using a placebo in an experiment (especially if the results are to be analyzed using a t-test). The cartoon is the work of Theresa McCracken and appears as #6864 on McHumor.com Free for non-profit use in statistics course such as in lectures and course websites.
• ### Cartoon: Placebo Immunity

A cartoon for use in discussions about the value of using a placebo in an experiment. The cartoon is the work of Theresa McCracken and appears as #7813 on McHumor.com Free for non-profit use in statistics course such as in lectures and course websites.
• ### Quote: Fuller on experiments

Every time man makes a new experiment he always learns more. He cannot learn less. is a quote of American inventor and author Richard Buckminster Fuller (1895-1983). The quote appears in his 1963 book "Operating Manual for Spaceship Earth".
• ### 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.
• ### Cartoon: Reproducible Results

A cartoon that might be used in teaching about the importance of replication in experimentation. The cartoon is #58 in the "Life in Research" series at www.vadio.com. Free to use with attribution in the classroom or on course websites.
• ### Webinar: Using Games to Teach Design of Experiments

April 27, 2010 Activity webinar presented by Shonda Kuiper, Grinnell College, and hosted by Leigh Slauson, Capital University. Educational games have had varied success in the past. However, what it means to incorporate games into the classroom has changed dramatically in the last 10 years. The goals of these games are to 1) foster a sense of engagement, 2) have a low threat of failure, 3) allow instructors to create simplified models of the world around us, and 4) motivate students to learn. This webinar uses the same reaction time game to demonstrate a simple 1- 2 day activity that is appropriate for introductory courses as well as an advanced project that encourages students to experience data analysis as it is actually practiced in multiple disciplines. In the introductory activity students are asked to spend 15 minutes playing an on-line game. Data collected from the game is used to demonstrate the importance of proper data collection and appropriate statistical analysis. The advanced project asks students to read primary literature, plan and carry out game based experiments, and present their results.
