Box and Whisker: Quick Construction Exercises

The LARGE POINTS in the app below represent data values. Greater values are further to the right. Lesser values are further to the left. Drag these points around and observe the changes in the box and whisker plot that take place.

What do you notice in the app above? What do you wonder? List your observations here.

Move the data points around to make the ENTIRE BOX AND WHISKER PLOT DISAPPEAR!

Describe a data set that makes the entire box and whisker plot disappear.

Move the data points around to make ONLY THE WHISKERS (at both ends) disappear. Make sure there's a BOX ONLY.

What did you do to make ONLY THE WHISKERS (at both ends) disappear? Describe a data set that causes this to happen.

The length of the BOX is said to be the INTERQUARTILE RANGE (IQR) of the data set. Create a data set for which the IQR = 6 units.

The HORIZONTAL SPAN (DISTANCE) between the MIN and MAX (ends of both whiskers) is said to be the RANGE of this data set. Create a data set for which the IQR = 6 units & the RANGE = 12 units.

Create a data set for which IQR = 4 units & RANGE = 12 units.
