Significance test between countries

[mils]

Hi SPSS community!!!

I have the following data:

EU4 France Germany Italy Spain
104 23 35 34 12
266 54 67 67 78
207 67 54 32 54


and I was wondering if is it correct to sig test each country "against" EU4 since this is the sum of the four countries.

My first thought was to sig test each country against each other and see if there are any differences.

Many thanks.

An ANOVA of the countries gives a test of whether any inidviudal countries differ from the "average" of all countries.

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.
