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?

Thanks!

generalization of the Mann-Whitney U test (AKA Wilcoxon rank sum) for

comparing two distributions. It assumes the criterion is measured on an

ordinal scale of measurement and tests the hypothesis that J population

distributions are equal. Basically all observations for the J groups are

pooled and rank ordered from low to high, the test is based on a comparison

of the sum of ranks within each of the J groups. A mean rank is simply the

mean of the rank transformed distribution.

1. How to preform Cuzick's test after a Kruskal-Wallis test?

,Dear Sirs

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

subcommand.

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?

Thank you
