  • A cartoon that can be used in discussions about sampling plans and the difficulty of implementing a plan (or in discussions of inclusion and exclusion criteria in an experiment). The "Dragon sampling" idea was due to Dennis Pearl of Penn State University. The caption came from the participants at a 2015 USCOTS breakout session as part of a caption writing activity facilitated by Dennis Pearl, Larry Lesser, and John Weber. The cartoon was sketched live during the session by British cartoonist John Landers (with the color version being finished during a second session). This is the first of two captions for this cartoon. All Landers copyrighted cartoons on CAUSEweb are free for non-profit educational use.

  • 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.

  • This complete lesson plan, which includes assessments, is based upon a data set partially discussed in the article "Female Hurricanes are Deadlier than Male Hurricanes." The data set contains archival data on actual fatalities caused by hurricanes in the United States between 1950 and 2012. Students analyze and explore this hurricane data in order to formulate a question, design and implement a plan to collect data, analyze the data by measures and graphs, and interpret the results in the context of the original question.
