Abstract
Frender and Doubilet suggest that Bousfield's ratio of repetitions (RR) is the best measure of clustering in free recall presently available. Conditioning only on the number of words recalled, they determine the mean ofRR in the absence of clustering. In this note the null variance ofRR is presented. This permits development of conservative significance tests based on the Cramér inequality.
