Among other things, what kind of differences among the countries are
you looking for. Paul Swank said, correctly, that if you are looking
for differences in mean value, that's an ANOVA problem. But
differences in mean don't capture the real differences in your data.
For example, France and Spain have the same mean value; but that
misses that Spain has by far the widest range, with both the lowest
and highest values in the data.
