Instructional Ideas

• If the class does not know how to create a box-and-whisker plot, provide a short lesson on how to do it by hand

Classroom Considerations

• Pupils should know how to calculate a five-number summary
• Some calculators will not graph two box-and-whisker plots on the same screen; sketch the plots on the same axis using the calculator's graph as a reference

Pros

• Contains extensions to use with the entire class
• Provides suggestions on how to differentiate the activity

Cons

• None
