Proportional Reasoning: Lessons from Research in Data and Chance

  • Proportional Reasoning: Lessons from Research in Data and Chance

    Jane Watson; J. Shaughnessy
    Two statistical tasks, one on comparing data sets, another on repeated sampling, both of which have powerful connections to proportional reasoning. Students' 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.
