Sampling & Survey Issues

  • A cartoon to be used for discussing the importance of efficiency in sampling. The cartoon was used in the April 2017 CAUSE Cartoon Caption Contest. The winning caption was submitted by Mickey Dunlap from University of Georgia. The drawing was created by British cartoonist John Landers based on an idea from Dennis Pearl of Penn State University. Three honorable mentions that rose to the top of the judging in the April competition included "Better to ask for help BEFORE you're drowning in data!," written by Larry Lesser from University of Texas at El Paso; "I guess I should have asked for more details before signing up for this "Streaming Data" workshop," written by Chris Lacke from Rowan University; and "On reflection, random sampling WITH replacement might not have been appropriate in this scenario," written by Aaron Profitt from God's Bible School and College.

  • A poem to illustrate the dependence between trials when sampling is without replacement. To set this poem up in the classroom, you might ask the students questions like: "If I want to put the Supreme Court Justices in a random order, I can pick one at a time without replacement. Before I pick the first Justice, do I know who it's going to be? Before I pick the last Justice, do I know who it's going to be?" The poem was written in 2017 by Larry Lesser from The University of Texas at El Paso.

  • 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.

  • A song to be used in discussions of the problems and challenges with modern polling (e.g. the use of Robo calling contact methods and the very low response rates making weighting to avoid bias more crucial than sampling variability issues). The lyrics were written in 2016 by Dennis Pearl from Penn State University and Lawrence Lesser from University of Texas at El Paso. The song may be sung to the tune of Bob Seger's 1978 hit "Old Time Rock and Roll." Musical accompaniment realization and vocals are by Joshua Lintz from University of Texas at El Paso.
