Yet another question about where to put StatCounter code on WP

I’m trying to add the statcounter to my main page in my blogger(http://www.shoganart.com/blogger) as well as my main website (http://www.shoganart.com)

First of all, for webhosting, I use BlueHost. Now I already went to statcounter and I wasn’t sure but I clicked on the W3c and got the code. I’ve read that you are supposed to put it somewhere in the index.php (near the bottom). I’m not sure how to go about doing this. Am I supposed to access this through WordPress or in “File Management” in BlueHost. I did find an index.php, but there was very little code and I don’t think this is right location…

‘<?php
/* Short and sweet */
define(‘WP_USE_THEMES’, true);
require(‘./wp-blog-header.php’);
?>

‘

Where do I find the right place?
