We present preliminary results from the statistical analysis of the correlation between the radio and far in- frared fluxes in different samples of groups and clusters of galaxies, and isolated galaxies. We use 1.4 GHz fluxes from the NRAO VLA Sky Survey (NVSS) and Faint Images of the Radio Sky at Twenty centimiters (FIRST), and infrared fluxes at 12, 24, 60 and 100 microns from Infrared Astronomical Satelite (IRAS) and 12 and 22 microns from the Wide-field Infrared Survey Explorer (WISE). We show variations on the behavior of this correlation for the different samples. This correlation has been studied by several authors for different samples isolated galaxies and groups of galaxies.
