“…Some of these six data aspects have received greater attention in the scientific literature than others. Specifically, the data aspect “overlap” has received a great deal of attention, with the Percentage of Nonoverlapping Data (Scruggs et al, 1987 ) as one of the first and most widely adopted quantification of effect size in SCEDs, and with other more recent nonoverlap indices as the most frequently used alternatives for the quantification of SCED effects (Jamshidi et al, 2022 ; Maggin, O'Keefe, & Johnson, 2011 ; Radley et al, 2020 ). The different nonoverlap indices have also been compared multiple times (e.g., Lenz, 2013 ; Parker, Vannest, & Davis, 2011 ; Rakap, 2015 ), and included in studies both with real data (e.g., M. Chen et al, 2016 ; Wolery et al, 2010 ) and with generated data (e.g., Giannakakos & Lanovaz, 2019 ; Tarlow, 2017 ).…”
