Europe: Median = 78, LQ = 77, UQ = 79 S. America: Median = 72, LQ = 70, UQ = 75

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

If we’d been asked for the median

Median = 62 hours

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.

The boxOne whisker

The other whisker

I’ll use the age data from the previous presentation.

The box can be any depth.

We need a scale.

I’ll use the age data from the previous presentation.

The diagram can easily be drawn using a cumulative frequency diagram.

Now draw a box and whisker plot from a given

set of data (i.e. not a cumulative freq

diag) P459 Q9
