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.
This activity explains the important features of a distribution: shape, center, spread, and unusual features.

A song describing how sample means will follow the normal curve regardless of how skewed the population histogram is, provided n is very large. The lyrics were written by Dennis Pearl and Peter Sprangers, both then at The Ohio State University. The audio recording was produced by The University of Texas at El Paso student Nicolas Acedo who also performed the vocals
