With so much Ghost Referral Spam and "(not provided)" these days it can be really difficult for anyone, much less someone new to working on their own website, to interpret Google Analytics data.
Historically, it's been pretty user-unfriendly and has really gotten worse over the years IMO. This is one reason I always recommend people use StatCounter, especially for lower-traffic websites (it's also good for comparing against what GA reports).
After a quick search, I didn't find too many good explanatory articles or videos for beginner detailing something simple like understanding Direct vs Referral vs Organic Search visits. This one (although using the old GA interface) does a decent job of giving the quick answer.
Just remember that there are TONS of caveats which I guess I'll have to try and explain in a blog post sometime later. Anyone else know of any good resources? http://www.whereoware.com/blog/direct-vs-search-engine-vs-referral-traffic/2011/06/
