In your GNBs find the Median life expectancy for any two continents from the four above. Once you have found this, find the Lower Quartile, Upper Quartile and InterQuartile Range for your two continents

Answers (in years) Europe: Median = 78, LQ = 77, UQ = 79 S. America: Median = 72, LQ = 70, UQ = 75 Asia: Median = 69, LQ = 65, UQ = 71.5 Africa: Median = 45, LQ = 38, UQ = 51.5

I’ll use the age data from the previous presentation. A box and whisker 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. The box can be any depth. minimum age One whisker The box The other whisker 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. median minimum age 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. We need a scale. 100 50 Age (years)

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