Hey, could I just ask you a quick question?
if i have two sets of numbers, eg:
list1 = 1,3,4,4,4 list2 = 1,2,4,5,6
and in R, i run the command:
wilcox.test(list1, list2, paired=TRUE, alternative="greater")
and say i get a p-value of 0.0001
Does this tell me that my values in list 1 tend to be larger than my
values in list 2, and that the difference in the distributions is
significant?
Read the third paragraph of the "Details" section of help page for this
function, which you can reach typing:
> ?wilcox.test
Or, if that's not clear enough, why not just try it
on a case with known result:
y <- 1:10
x <- y + runif(10)
wilcox.test(x, y, ....)
