Box plots of host galaxy stellar mass (M_★, top), SFR (middle), and Eddington ratio (λ_Edd, bottom) for the four AGN populations, in three redshift intervals. Whiskers extend to 1.5 × IQR, and individual points beyond this range are shown as single circles. For classes represented by a single measurement (e.g. BLAbs at low redshift), the individual data point is plotted directly. Median values and IQRs for different redshift intervals are presented in Tables 7, 8, and 9.
