“…The third strategy suggested by researchers is that instruction should begin with an informal approach to statistical inference before introducing formal statistical inference (e.g., Chance & Rossman, 2006;Erickson, 2006;Garfield & Ben-Zvi, 2008;Garfield, delMas, & Zieffler, 2012;Rubin & Hammerman, 2006;Weinberg, Wiesner, & Pfaff, 2010;Zieffler, Garfield, delMas, & Reading, 2008). By building on informal approaches, educators can better support students' learning of statistical inference concepts because new knowledge is constructed from the learner's prior knowledge, and thus making formal procedures more accessible.…”
