Hi, I am very confused with constructing the wilcox.test in R. I have two populations 'original' and 'test'. I want to know if the 'test' is generally 'lower' than original. I use alpha of 0.05.
So do I write the function as wilcox.test(original, test, alternative="l")? or wlcox.test(original, test, alternative = "g")? or wilcox.test(test, original, alternative="g")? or wilcox.test(test, original, alternative="l")? How do I interpret the p-value given my criteria? Do I reject null when p-value less than 0.05? or greater than 0.95? Not a statistics major here so I'm really confused. Need some help. Thanks. -- View this message in context: http://old.nabble.com/wilcox.test-construction-in-r-tp26148779p26148779.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
