[R] Glitch in Kruskal-Wallis test?

[Jenny Liu]

Hi everyone,
I have been running a K-W test with the attached data, PupMort1. My code:
kruskal.test(Prop~Temp,data=PupMort1)
However, I found that I get the exact same result when I change the x-values, as
in the attached data PupMort2.
Test run with PupMort1Kruskal-Wallis rank sum testdata:  Prop by Temp
Kruskal-Wallis chi-squared = 6, df = 6, p-value = 0.4232
Test run with PupMort2Kruskal-Wallis rank sum testdata:  Prop by Temp
Kruskal-Wallis chi-squared = 6, df = 6, p-value = 0.4232
Does anybody know why this is happening?
Thank you!
Jenny
