ab: Summary: This article presents two statistical tasks, one on comparing data
sets, another on repeated sampling, both of which have powerful
connections to proportional reasoning. Studentsâ€™ work and reasoning
on these tasks are included, as well as suggestions for ways to use
these tasks with middle school students to connect statistical thinking
to proportional reasoning. (Contains 2 figures.) (ERIC)
