Judging ease of reading
Book, How Do I Love Thee? Let Me Count the Words. "When Amazon gets the right from a publisher to let readers "search inside" a book, Text Stats tallies the average length of a sentence and amasses little piles for each word used. (Or big piles, as in the case of the King James Bible, for example, where the count for "loin" is 1,548; "behold," 1,426; and "lord" 7,082.) The software then ranks a book for clarity and ease of reading on a variety of indexes. For example, "The Story of Babar" has a Flesch-Kincaid Index score of 6.1 (sixth-grade level), the same as "Everything Is Illuminated" by Jonathan Safran Foer. Their "fogginess" quotients, an index similar to Flesch-Kincaid, are very close, too, though the Foer book is slightly less clear — 8 percent of its words are "complex," compared with 7 percent for "Babar." Text Stats also produces concordances, lists of the 100 most-used words in a book."
