Statistics book

[blerg]

I need a statistics book to help me understand concepts like skewness and kurtosis.
I don't need a really advanced book, just one that will hopefully give me an understanding about the topics and make me able to implement them on my own.
I have very little background statistics or probability, but I have about a graduate level education in pure math (just to get an idea of where i'm at)

Please recommend a book to me.

Thanks.
I picked up the book by Kendall. Seems to be just what I need.
