What is the general method for creating graphs from raw text

[GeorgeMendes]

I consider myself pretty good with MATLAB when it comes to engineering classes. However now I have survey data for a social experiment and it is throwing me completely off. My data is a spreadsheet with every row being responses to multiple questions from a single person. I have both text answers(demographics, y/n, etc.) and their corresponding answers to discrete numerical questions ("on a scale from 1-4...?") in each row.

So far all I have is [num,text,raw] = xlsread('file.xls') and the text data and numerical data are split.

What do I need to do in order to isolate and plot numerical data for a specific demographic? Should I stick with excel on this one?
