Fifty-seven quasars were observed with the NRAO/sup */ 3-element interferometer. Fifty-two of the quasars comprise a complete radio/optical sample, consisting of all quasars in a particular area of sky with radio and optical flux densities above specified limits (Schmidt, 1976). Radio structures were determined at lambda3.7 and 11.1 cm. These data were combined with data from other complete samples to perform statistical studies of quasar linear sizes. The correlation between size and redshift is demonstrated. The quasar distribution is assumed separable into a space density function, optical and radio (color) distributions. These distributions are derived for different linear size ranges. The results favor but do not prove an underlying size-radio luminosity relation. Turner's fractional rank method was tried with inconclusive results. Models with luminosity evolution were tested with rank correlation statistics. In the course of the observations at least two of the quasars, 4C32.69 and 4C39.27, were found to have highly luminous radio jets connecting the nucleus to one of the outer radio lobes.
