This article describes an SPSS program that computes four common clustering measures used to analyze free recall of information from categorized lists. This program computes Cohen, Sakoda, and Bousfield's ratio of repetition (RR), Wallace and Underwood's modified ratio of repetition (MRR), Roenker, Thompson, and Brown's adjusted ratio of clustering (ARC), and Bousfield and Bousfield's deviation score (DS) for stimulus lists with an unlimited number of categories and items per category.
