Overlaid histograms of the planetary radius distributions for planets in single-transiting systems with radius values less than 6 R _⊕ (blue) and compact multiple planets (pink) after performing a 95th percentile quality cut on both samples. The median of each sample is plotted as a vertical line of the same color. The median lines are off-shifted by 0.301 R _⊕. Our quality cut threw out 15 planets from our study that had σ _Rp /R _p > 0.2299. The two-sample K-S test, Mann–Whitney U test, and Anderson–Darling k-sampling test were reapplied to the planets surviving the quality cut. Tables 12 and 13 display the significance of our statistical tests that endured our jackknife resampling.
