Note: I am very new at using SAS and I am assuming the naming I used for the data has screwed up how the program is interpreting it.  I am attempting to do a Wilcoxon Rank-Sum test on the distribution of serum estradiol.  Any help would be appreciated as I am just a commoner and a foreigner when it comes to programming and writing :smileyblush:

Hi,

Serum is an analysis variable. You are using it as character variable instead of numeric.

[Reeza · Accepted solution]

data ranksum; input serum $ race;

The $ above tells SAS to import it as a character variable. Remove that, and it will import it as numeric and your analysis will run. If anything race should be the character variable.

data ranksum; input serum race $;

That would make more sense I guess I got a bit confused on what the $ was even denoting.  Thank you for the quick help!
