Profiles of the average molecular outflow mass, momentum, and energy rates per outflow lobe for different protostellar evolutionary classes (Class 0, Class I, and flat spectrum). For the Class 0 sources, we show the average rates with and without inclusion of the high-velocity jet component. All results shown are inclination corrected. In creating these plots, the Class 0 source HOPS 408 was not included because its outflow is barely resolved, and the flat-spectrum sources HOPS 166 and HOPS 194 were not included because they have significantly higher bolometric luminosity (>10 L _⊙) and significantly higher core masses compared to other sources in this study. The dispersion of outflow rate values for each evolutionary class is approximately a factor of 2.
