Helping me to continue to connect National Poetry Month with Mathematics Awareness Month (with its theme of "Mathematics, Statistics, and the Data Deluge") is the following poem by Halifax mathematician Robert J. MacG. Dawson, and found in the September 2011 issue of The Mathematical Intelligencer.
Dawson's poem "Statistical Lament" will be recognizable to many as a parody of Joni Mitchell's "Both Sides Now." (Still more math songs and parodies may be found in earlier blog postings -- on 5 June 2011, 14 February 2011, 4 January 2011, and 23 April 2010.)
