This is one of those questions where I feel it would be helpful to know 
more about what you are doing. I mean, if you have a large number of 
data values, perhaps they are already in a file, and you need help 
reading them in.

At the very least, you surely want to type the values in and keep them - 
in case, perhaps, you make a mistake - so why not use a list:

data={2,67,31};

Map[f,data]
