A cartoon that invites conversation about the type of biases that may result from the way a pollster handles the logistics of taking a survey and thus the importance of careful planning.  The cartoon was used in the February 2022 CAUSE cartoon caption contest and the winning caption was written by Don Bell-Souder a student at University of Colorado, Boulder. Two alternative captions with the same basic learning object are “Selection bias is in the eye of the beholder” written by Sarah Arpin and “ACME polling finds that bootstrapping still reflects self-reporting bias.” Written by Rosie Garris who are also both students at University of Colorado, Boulder. The cartoon was drawn by British cartoonist John Landers (www.landers.co.uk) based on an idea by Dennis Pearl from Penn State University.

A song for discussion of the uses of weighting. In particular, Verse 1 hits the weighted mean (with a nod to Simpson’s paradox), Verse 2 connects with how/why poll data are weighted to help the sample more accurately reflect population characteristics, which can launch a discussion of what we adjust for (probability, sample design, demographics) and how (raking, matching, propensity weighting). This can be supported by examples in GAISE (https://www.amstat.org/docs/default-source/amstat-documents/gaisecollege...) and apps (e.g., https://sites.psu.edu/shinyapps/2018/12/03/weight-adjustment-in-surveys/). Finally, the Bridge touches on weighted regression. Lyrics by Larry Lesser from The University of Texas at El Paso; may be sung to the tune of the 1981 hit "The Waiting" by Tom Petty.  The song received an honorable mention in the 2023 A-mu-sing competition.  Thanks to UTEP’s Jose Villalobos for the song title and for contributing backing vocals and guitar to Larry’s on the recording.

A joke to initiate a conversation about the importance of understanding your Sampling Frame when conducting surveys.  The joke was written by Larry Lesser from The University of Texas at El Paso in 2021.

A cartoon that can be a vehicle to discuss the old GIGO adage (Garbage In Garbage Out) indicating how poor data may well produce poor results. The cartoon was used in the September 2022 CAUSE cartoon caption contest and the winning caption was written by Jonathan Boucher, a student at Colorado University in Boulder.  The cartoon was drawn by British cartoonist John Landers (www.landers.co.uk) based on an idea by Dennis Pearl from Penn State University.

A song to encourage students to use critical thinking skills in evaluating a statistic published in the media. The 2002 JSM paper (http://www.statlit.org/pdf/2002BestASA.pdf) of sociologist Joel Best and feedback from Milo Schield gave Lawrence Lesser (The University of Texas at El Paso) inspiration to explore what it means to say statistics are socially constructed. The song is a parody of the Beatles' "Lucy in the Sky with Diamonds." The lyrics were originally published in the August 2016 Amstat News. Audio of the parody was produced and sung by students in the commercial music program of The University of Texas at El Paso.

This song covers some major real-world examples in the history of random sampling. The lyric was written in 2017 by Lawrence M Lesser from The University of Texas at El Paso and can be sung to the tune of theHarry Casey and Richard Finch song “(Shake, Shake, Shake) Shake Your Booty” that was a 1976 #1 hit for KC and the Sunshine Band.  Audio of the parody was produced and sung by students in the commercial music program of The University of Teas at El Paso.
