Left panel: Distribution of stellar metallicity for a sample of non-void galaxies that mimics the r-band absolute magnitude distribution of void galaxies. Right panel: The galaxy age distribution for the same samples. The filled gray histogram represents the distribution for non-void galaxies, while the red histogram represents the distribution for void galaxies. A vertical dotted black line indicates the median for the non-void sample, and a dashed red line indicates the median for the void sample in each panel. Each panel also includes the p-value from the KS statistical test.
