Want google analytic code

I am running a wordpress site i.e. http://www.newdelhilab.com
I want to use google analytic for my site to track my visitors and for that I created an google analytic account and pasted the code here
Appearance> Editor> Footer.php
but now the problem is that I can see the code on source page of all the pages available but can see it at my home page.

Now what should I do to track my home page? How to include the code there?
