The boxplot is obtained from the set of -coordinates of the points. Move the slider to select the number of points. Move the points to change the data. The detect ouliers button enables the 1.5 * IQR outlier rule to produce a modified boxplot.
Think about:
  • Why doesn't the boxplot for three points have whiskers?
  • Why is it that some point values don't influence the boxplot?
  • What is the fewest number of points required to produce the 5-number summary {1,2,3,4,5}? What are the data values?
  • What is the fewest number of points required to produce the 5-number summary {1,2,3,4,6}?
  • What is the maximum number of outliers in data set of size 10?
