Thanks to both. I'm reading up on these methods you've supplied at 
http://www.ruby-doc.org/core/. It looks like the .map method is a 
synonym for .collect. I'll read up on .inject next.

Yes. In fact, both of these work---liking ruby's flexibility here.

#data = raw_data.split(/\;/).map { |raw| raw.to_f}
#data = raw_data.split(/\;/).inject([]) { |a,i| a << i.to_f }
