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.
