My Most Controversial Books

Librarything has a new feature that measures the standard deviation of members star ratings. Kind of interesting: (click to enlarge)

I don't seem to have a very controversial library. Here's the best that I could muster:

Deviation Rating Title
1.356 3.38 The Man Without a Country by Edward Everett Hale
1.317 3.55 The Marble Faun by Nathaniel Hawthorne
1.18 4.21 The Bible: KJV
1.18 3.63 Reflections on the Revolution in France by Edmund Burke
1.142 3.53 Prolegomena to Any Future Metaphysics by Immanuel Kant
1.134 3.93 Chanticleer and the Fox by Geoffrey Chaucer
1.132 4.18 Catechism of the Catholic Church by United States Conference of Catholic Bishops
1.127 3.61 What to Expect When You're Expecting by Heidi Murkoff
1.111 3.23 Tom Brown's School Days by Thomas Hughes
1.093 3.56 On the Nature of Things by Lucretius

(Word verification: "netsated" Is one ever?)

I need to go over mine again. I have to admit I didn't really understand it. Too much like math. (check my library - maybe one or two books even remotely mathematical and they were for homeschooling purposes) The whole thing was rather confusing - the one sentence explanation didn't help. Maybe some family member will waltz thru the room and bail me out.
(I did do my original examination of the results on the down-low while at work, so maybe I wasn't using my whole brain...but that probably doesn't explain my problem.)

Ellyn, it basically measures how disparate the ratings for a particular book. If one book gets rated an 1 by one person and a 5 by someone else, it'll have a higher standard deviation than a book getting 2 stars from one person and 3 stars from another...

OK, yeah, now I think I understand. I'm going back now to re-examine my library. This could be interesting.

It's just the square root of the variance.
