Hello,
I'm trying to run kruskal test on some data but the p values seemed way too
low. So I tried it on some similar data and still got p-value =
1.611e-09. I'm sure it is a simple mistake but I can't figure it out.
Below is my data and code. Could it be because there are some miss data /
NAs in the data set?? If so, could some one point me towards a solution??
Thank you for your time.
David
mydata <-read.csv("http://doylesdartden.com/R/test.csv";, sep=",")

data: mydata
Kruskal-Wallis chi-squared = 36.3952, df = 1, p-value = 1.611e-09
