Search query from Google Webmaster Tools isn't found in my SERP

I write a blog at blogger.com. I am using Google Webmaster Tools on my blog.

In my Webmaster tool dashboard, I can see that a particular search query has an average position of 5. See the attached screenshot below for reference:

However, when I search the exact search query in Google, I don't see my blog in the results (at least not in the first 4 pages).

Can anyone explain this to me? Or am I misinterpreting the Webmaster Tools data?

ANSWER:

The data from Google Webmaster Tools is misleading and notoriously inaccurate at best.

Take it with a pinch of salt.

Also bear in mind, this is the average position over the specified duration rather than a categoric "this is where you rank for this keyword".
