Hi Spikelema,
Good question!
Check out this article:
Evaluation and Exploitation of Stats
It should give you the basic information you need.
If you are not so experienced in poker, getting into stats in a big way might not mean as much as it could.
Play from a starting hands chart for a bit, following the guidelines for post-flop play for a bit so that you get a feel for the game.
Then the stats info will make much more sense.
Make sure you spend some study time and review time each day too.
♦ Study an article, and review any hand evaluations received from pref session
♦ Play some poker, looking for situations covered in the article and mark the hands in HM2 -- also mark any hands where you don't have a clear understanding of what to do.
♦ Review your hands, posting the ones you marked in the hand evaluation forums.
♦ Go to Step 1 
Best of Luck!
