Need input on Data Analysis

Hi,

I have a problem at hand that I need some input/advice for. Here is what I have:

1. I have a large IR text file consisting of several queries.
2. For every query, a set of documents are returned with their final relevance as 0 or 1 for the given query
3. Every document returned has a set of features values returned (like 0.123, 0.0456) etc.

Task is to analyse this data and provide some graphs. If any modeling can be done on this data, then even better.

Question is:

1. What kind of data analysis (please specify exact terms like mean, median, k-means, linear regression etc.) I can apply?
2. What kind of graphs would be useful to show in this scenario?

Much thanks
