"Naked Statistics" by Charles Wheelan is a very approachable entry level book. As opposed to a textbook, it's something that can be read casually in a relatively short amount of time, while still building a solid intuition on the subject.

Was about to buy this book, but from the reviews it seems the author is using very US centric sports (Baseball, football) to explain things. So if you are from outside the US and have no understanding of the sports you will struggle.
