A song that may be used in discussing the difference between cluster sampling and stratified sampling and the value of them when you have groups known to be homogeneous for the variable under study. The lyrics were written by Mary McLellan from Aledo High School in Aledo, Texas as one of several dozen songs created for her AP statistics course. The song may be sung to the tune of Mike Chapman and Nicky Chin’s 1979 song "Kitty", popularized by Toni Basil in her 1981 recording of the song as "Mickey".
