• ### Cartoon: The Relationship Graph

A cartoon to help in teaching the importance of labeling the axes of a graph. The cartoon is number 833 from the webcomic series at xkcd.com created by Randall Munroe. Free to use in the classroom and on course web sites under a creative commons attribution-non-commercial 2.5 license.
• ### Data Collection+Examples: STATS 46 Issue 46, Fall 2006

This issue contains an article that provides an example of a paired samples test related to flying and gliding. It also includes an article about understanding confounding from lurking variables using graphs. Other articles include: a short description about what the t-tests actually tests, an interview with David Moore about why 30 is the "magic" number, a discussion about whether or not outliers should be deleted from a data set, a discussion of observational studies, and a simulation piece about random numbers from non-random arithmetic.
• ### Data Collection+Examples: STATS 47 Issue 47, Spring 2007

This issue contains an interview with Sallie Keller-McNulty and an article about which came first -- the chicken or the egg. Other articles include a discussion related to an AP Statistics example of seeing the trees for the forest (this focuses on understanding variability between groups and within groups), a discussion of how high r can go, a simulation piece focused on shrinking students, poisoned children, and bootsraps, and an example of a permutation test of the Challenger O-Ring data.
• ### 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.
• ### Quote: Adams on Assumptions

...the most misleading assumptions are the ones you don't even know you're making is a quote by English author Douglas Noel Adams (1952-2001) that can be used in teaching the importance of understanding the assumptions being made that underlie statistical inference. The quote is from the 1990 book "Last Chance to See" that was co-written with Mark Carwardine. It is part of a passage that Adams wrote about his experience watching a silverback gorilla in Zaire and trying to imagine what the animal was thinking about him.
• ### Webinar: Introducing Informal Inference Using Data-Centric Lab Exercises

January 11, 2011 T&L webinar presented by Rakhee Patel(University of California - Los Angeles, UCLA) and hosted by Jackie Miller (The Ohio State University). Since formal hypothesis testing and inference methods can be a challenging topic for students to tackle, introducing informal inference early in a course is a useful way of helping students understand the concept of a null distribution and how to make decisions about whether to reject it. We will present two computer labs, both using Fathom, that illustrate these concepts using permutation in a setting where students will be answering interesting investigative questions with real data.
• ### Webinar: Building a Statway to Heaven

February 8, 2011 T&L webinar presented by Uri Treisman (Charles Dana Center, University of Texas at Austin) and hosted by Jackie Miller (The Ohio State University). Developmental education in America's community colleges has been a burial ground for the aspirations of our students seeking to improve their lives through education. Under the leadership for the Carnegie Foundation for the Advancement of Teaching and the Charles A. Dana Center, nineteen community colleges and systems are building accelerated pathways to and through developmental education with the goal of helping students with low levels of mathematical preparation complete a college credit bearing, transferable statistics course within one year. Uri will describe the work to date, the challenges the initiative faces, and the underlying ideas of improvement science that are driving its development.
• ### Quote: Powell on Experts

Experts often possess more data than judgment. is a quote by former U.S. four-star general and Secretary of State Colin L. Powell (1937 - ). The quote is found in lesson three in the article "Quotations from Chairman Powell: A Leadership Primer" by Oren Harari originally published in 1996 in "Management Review".
• ### STATS Issue 50 Spring 2009

This issue contains articles on: The predictive model used by the website FiveThirtyEight.com during the 2008 Presidential election, the design and implementation of an election day exit poll by statistics students, a description of the randomization measures taken to ensure fairness and transparency in the awarding of development grants to farmers in the Republic of Georgia, an explanation of the Item-Matching problem and the Coupon-Collecting problem, together with R code for simulating both problems, and a review of the book, Applied Spatial Statistics for Public Health Data.
