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 teach the idea that the average of independent measurements are more reliable than individual measurements from the same process. The joke should help start a discussion of the importance of the independence assumption in this idea. The joke was written by Dennis Pearl, Penn State University and Larry Lesser, The University of Texas at El Paso in September, 2022.
An interesting sestina poem to discuss measurement scales and can also be used while discussing spurious correlations if the teacher provides a guiding question such as “What part of the poem describes the relationship between quantitative variables, rather than just descriptions of quantitative variables? Are those relationships examples of 'Spurious Correlations' (per the title of the poem)? Explain briefly." If the students need further help, the instructor might suggest that they focus on the second to last stanza. The was written by Jules Nyquist, the founder of Jules' Poetry Playhouse, a place for poetry and play and published in the Journal of Humanistic Mathematics (2022) v. 12 #2 p.554.
A poem generally celebrating statistics. The poem was written by Sally Maughan and was chosen as the winner of an online contest seeking a Pi-Ku in the online mathematics education journal Aperiodical in 2020. A "Pi-ku" is like a Haiku except, instead of a 5-7-5 structure, it uses a 3-1-4 structure (the first three digits of π.
A cartoon that can be used in discussing the issue of selection bias. The cartoon appeared as number 2618 (June, 2022) in the web comic xkcd by Randell Patrick Munroe (http://www.xkcd.com/2618/).
A cartoon to illustrate the difference between the population of interest and the sampling frame for a survey. The cartoon was drawn by British cartonist John Landers in May 2021 based on an idea from Larry Lesser (University of Texas at El Paso) and Dennis Pearl (Penn State University).
A joke to help in a discussion of how a well designed experiment helps to reduce the variance of the response variable. The Joke was written by Larry Lesser (The University of Texas at El Paso) and Dennis Pearl (Penn State University) in Februrary 2021.
Note - when the joke is spoken there is no need to say the parenthetical part - simply pronounce the word "variants" to sound like "variance".
A poem to help in discussing matched-pair designs. UTEP Professor Larry Lesser wrote this poem on February 1, 2021, using end-rhyme couplets to convey (literally and figuratively) tradeoffs of a design with matched pairs. Note that the rhymes are not always perfect, a reflection of how it can be impossible to match subjects perfectly. Also note how the would-be final couplet is ruined by losing its second line, just as you effectively lose two subjects when one subject in a pair chooses to drop out of your study.
