I am told that I need to use the Kruskal-Wallis
Test to find the mean. However, I have no idea of
how to interpret the results. What exactly is the
mean rank, for example of income, telling me?

I use Spss version 7.00 for Windows in order to test whether there is a
linear trend between 3 different groups.
I use the Noneparametric test command with the K independent tests
As a result i receive the Kruskal-Wallis value but not the Cuzick's value
for linear trend.
Does anybody know how to obtain the Cuzick's test value?
