The need for an increased use of statistical data and quantitative analysis in many areas of science policy is emphasized in this report of the hearing on science evaluation methods used in Great Britain. The testimony given by Professor Benjamin Martin of the Science Policy Research Unit at the University of Sussex in England explains how quantitative information is used by the British in developing policies for science. Appendices consist of the selected papers by Professor Martin and his colleague Professor John Irvine and also contain seven critiques of Martin and Irvine's methodology. (ML)
