The Spearman Experiment was an Australian television series, hosted by Magda Szubanski that counts down Australian pop culture's most defining people and topics based on a public poll commented on by various Australian 'celebrities'. The series began development in May 2009, and was officially announced in early August 2009. The show is named for Charles Spearman, who developed Spearman's rank correlation coefficient, the statistical technique used to survey the public to produce the show's rankings.
