Abstract
Bias in the counting of quasars can arise partly from the scatter of intrinsic brightness and partly because of the shapes of quasar spectra. The corresponding selection effects can be eliminated for any cosmological model assumed. This procedure will be important for the evaluation of future catalogues of radio sources. At present, no decision can be made, from a statistical count of quasars, between steady state and other cosmological models.
