Abstract

November Vol VIII The British Journal of Statistical Psychology Part I1 TEST RELIABILITY ESTIMATED BY ANALYSIS OF VARIANCE' BY CYRIL BURT Hisiorical Nore. The idea of determining the ' precision ' of an estimated quantity from a series of repeated measurements is due originally to Gauss (Theoria Combinationis Observationurn, 1809).
