I have tried all kinds of test in spss in order to find out if there are any significant difference in compliance between different citys.

I have 16 citys and for each city i already calculated compliance in percentage.

I want to see if there are significant change in compliance (which it seems to be) but when i use kruskall wallis in spss it turns out to be 0.451 no matter what kind of numbers i put, so something is wrong, but what?

name of citys that i translated into numbers eg london = 1, dublin = 2 etc

1. 0.56

2. 0,31

3. 0.90

so on until 16

Grouping variable is 1 to 16 and test variable is compliance.

what do i do wrong?

please help me
