Cumulative distribution of metallicity of our broad SE SNe, measured using PP04 (included for literature comparisons) and more up to date M13 method. Literature samples of Type Ibc metallicities from Anderson et al. (2010), Modjaz et al. (2011, 2020), Sanders et al. (2012) are also shown for comparison, which were calculated using the PP04 method. We see a clear statistically-significant difference between the metallicities of our sample compared to the average SE SN host metallicity.
