Instructional Ideas

  • Discuss whether the type of data display used will affect the type of calculations needed to compare the populations
  • Provide several dot plots to have the class compare and determine whether there is a difference
Classroom Considerations

  • Classmates should know how to calculate the mean absolute deviation
Pros

  • Includes a link for an online stopwatch
  • Highlights the location in the lesson where the mathematical practices are incorporated
Cons

  • The resource references a previous lesson that comes later in the series
