Armspans
Do the armspan lengths of 12-year-old NZ boys tend to be bigger than the armspan lengths of 12-year-old NZ girls? The focus of this lesson is on comparing two samples and making an inference about populations from samples. Students’ previous work on boxplots and work on sampling ideas are combined in this activity.
