  14. The projected population of the U.K. for 2005 ( by age ) A box and whisker diagram can easily be drawn using a cumulative frequency diagram. I’ll use the age data from the previous presentation. The box can be any depth. minimum age One whisker The box The other whisker median maximum age lower quartile upper quartile

  15. minimum age median maximum age lower quartile upper quartile The diagram can easily be drawn using a cumulative frequency diagram. The projected population of the U.K. for 2005 ( by age ) I’ll use the age data from the previous presentation.

  16. 0 50 100 Age (years) The diagram can easily be drawn using a cumulative frequency diagram. The projected population of the U.K. for 2005 ( by age ) I’ll use the age data from the previous presentation. We need a scale.

  17. Now draw a box and whisker plot from a given set of data (i.e. not a cumulative freqdiag) P459 Q9
