Educators fear that retention of course concepts in science and mathematics often lags in the time after course completion. Few studies have explored patterns of retention in statistics courses. Tintle et al. (2012) found poor retention of statistical concepts among students in a first statistics course four months after course completion at a single institution, with some improvement among students taking a modified version of the course centering on simulation-based inference. We will report findings from a multi-institution study of retention both four-months (680 students) and 16-months (95 students) after the completion of an algebra-based statistics course, discuss retention patterns on a variety of key statistical concepts, and similarities and differences in retention based on a variety of curricular choices (e.g., use of simulation-based methods).
