Query: Good refresher

I'm mid-30s and needed a book on statistics that i can use to refersh my memory. I didn't want to buy the book used in college, so i opted out for this book. It gives you the basics and fundamentals of stats. I didn't expect it to go deep into every area of statistics. I guess it depends on the person who reads the book, but it's easy to understand and the problems that the authors uses are easy to follow. Good enough for me.
