Several individual indicators from the Times Higher Education Survey (THES) data base—the overall score, the reported staff-to-student
ratio, and the peer ratings—demonstrate unacceptably high fluctuation from year to year. The inappropriateness of the summary
tabulations for assessing the majority of the “top 200” universities would be apparent purely for reason of this obvious statistical
instability regardless of other grounds of criticism. There are far too many anomalies in the change scores of the various
indices for them to be of use in the course of university management.
