• ### Song: 50 Ways to Leave Your Lover

A song for teaching about the multiplication rule.  Using the popular topic among young adults of relationships, the multiplication principle is memorably illustrated by having Paul Simon's #1 hit song (which states only a half-dozen ways to leave your lover, not 50) revisited to show 50 literal paths for ending a relationship: (5 reasons for the decision) X (5 methods to relay the decision) X  (2 options for handling acquired stuff). The lyrics were written by Larry Lesser from The University of Texas at El Paso to the tune of Simon’s same-titled 1975 song.  The audio recording features vocals by Abeni Merryweather and production by Abeni Merryweather  from UTEP's commercial music program.  The song tied for second place in the 2023 A-mu-sing contest.

The structure of the problem in the song is similar to Exercise 3 in the progressive curriculum sequence outlined in the Spring 2024 Journal of Mathematics Education at Teachers College article “A Problem-based Curriculum to Develop the Multiplication Principle for Counting”: https://journals.library.columbia.edu/index.php/jmetc/article/view/11949/6300

• ### Poem: Pedestrian Deaths by Age

This poem, written in July 2024 by Lawrence M. Lesser of The University of Texas at El Paso, is in the form of a bimodal distribution, reflected in the poem’s real-world context.  Before showing the poem, a teacher could first ask students to reflect on what they would expect a histogram of ages of pedestrians killed (or severely injured) to have and why (chances are some of their suggested rationale will  be captured in the poem!).

Afterwards, students wanting to examine or discuss real-world evidence of such a distribution may look for data on their own, or be shown section 1.1.3 of

Roe, M., Shin, H., Ukkusuri, S., Blatt, A., Majka, K. et al. (2010), “The New York City Pedestrian Safety Study and Action Plan Technical Supplement,” New York City Department of Transportation. http://www.nyc.gov/html/dot/downloads/pdf/nyc_ped_safety_study_action_plan_technical_supplement.pdf .

This visual poem may also inspire students to write their own short statistics poem using (and connecting to) a data set with a differently shaped distribution.

• ### Poem: Statistic Acrostic

Statistic Acrostic is a poem by statistics educator Lawrence Mark Lesser and biostatistician Dennis K. Pearl that covers several statistical concepts using only 26 words (one starting with each letter of the alphabet). It was written in 2008 as a response to an example and challenge from JoAnne Growney in her poem “ABC, an Analytic Geometry Poem” in a 2006 article in Journal of Online Mathematics and Its Applications.  To expand the usefulness of this form for educational objectives, a teacher could have students not follow the 26-letter alphabet, but generate an acrostic from a statistics word or phrase.

• ### Song: Mean

A song to teach about when the mean versus the median is better for describing a distribution. The lyric was authored by Lawrence Mark Lesser from The University of Texas at El Paso. The song may be sung to the tune of Taylor Swift's Grammy-winning 2010 hit "Mean". Free for use in non-commercial teaching.

• ### Poem: Statistical Clerihews

These clerihew poems (chronologically by statistician) written by Lawrence Mark Lesser from The University of Texas at El Paso were written in 2023 and appeared in the April 2024 Amstat News.  Each clerihew poem takes a famous statistician and (like all clerihew poetry) starts with their name and finishes the two couplets with playful or quirky details about their career or life.  Such poems could be used to humanize the class and because of the short simple form involved students could be invited to create their own about other statisticians.

• ### Poem: Expected Value Haikus

This haiku collection by Lawrence Mark Lesser from The University of Texas at El Paso was written in 2020 and won second place in the 2021 A-mu-sing Competition.  Each haiku in the collection addresses some property or real-world application of expected value that can be explored in class: the math and psychology in the structuring of an internationally syndicated game show (Deal or No Deal), tree diagrams (that students can do a calculation to verify in a realistic popular context of college basketball, showing how the EV need not correspond to the most likely outcome), an engaging probability paradox (in the context of the most popular animal Americans own as pets), the interaction with utility when making consumer decisions, a concrete visual analogy for a distribution’s expected value (inspired by Figure 2 of Martin’s July 2003 JSE article), and the concept of an estimator’s bias, and the how EV and mean express the same idea but in different contexts (random variable versus a sample, population or probability distribution).

• ### Cartoon: Acme Polling

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.

• ### Poem: With Statistical Means, She Writes

A poem written in 2023 by Larry Lesser from The University of Texas at El Paso that can offer a vehicle for students to reflect on parallels (in language or process) between poetry and statistics.  The poem was first published with commentary in the Autumn 2023 issue of Consilience.

• ### Video: Lifetime Achievement Trophy

A video from the 2019 US Conference On Teaching Statistics where Dennis Pearl from Penn State University is introducing the winner of that year's CAUSE/USCOTSLifetime Achievement Award in Statistics Education.  He tells a story that can be useful in teaching the lesson that linear regression is inappropriate for making predictions well outside the range of the data. The story is loosely based on the phone call he made in ordering the trophy for the award.

• ### Song: STATS

A song presenting common hypothesis tests and the steps in doing them with lyrics by Jamie Tan Xin Yee, Joelyn Chong, Deston Tang, Christine Sia, Nellie Lee, Josiah Tan, and Lee Yi Yuan who were all students at Singapore Management University taught by Rosie Ching Ju Mae.  May be sung to the tune of "LOVE" by Bert Kaempfert and Milt Gabler and recorded by Nat King Cole in 1965.  The vocals and guitar soundtrack on the audio were done by Joelyn. Editing of the soundtrack was done by the entire student team.The song placed tied for second in the 2023 A-mu-sing competition (see associated publicity).
