Sigma values from a selection of statistical tests for the sample with individual galaxies and their sample CCSNe removed from the analysis as a test. While removing individual galaxies from the sample, and thus typically only one or two CCSNe, will not have a major effect on the resulting AD test values, the arbitrary removal of Arp 299 and its 6 Type IIb/Ib SNe would make the discussed trends non-existent. Open and closed symbols show the values for samples with the host SNR of ≥0.0 and ≥0.5 CCSN yr⁻¹, respectively. Data points are not shown in cases where the removal of the galaxy is irrelevant for the comparison between the analysed samples. With the large number of hosted sample CCSNe, the removal of the LIRG Arp 299 with a yielded young starburst age also has the largest weight in the jackknife resampling averages of the p-values for each set of comparisons, and result in mean values of θ_p ≥ 0.017 (≤2.4σ).
