We analyze the optical variability of low-redshift quasars (0.4 < z < 0.5) using ZTF data. By dividing the sample into double-peaked, intermediate, and non-double-peaked spectral classes, we investigate how variability (Fᵥₐᵣ) correlates with physical and spectral properties. In addition to variability trends, we examine systematic differences in black hole mass, Eddington ratio, and line characteristics across the subsamples. These results provide insight into the physical distinctions among quasar types and the mechanisms driving their diversity.
