The Readability calculations estimate how easy it is to read and understand the text of a book. The Fog Index was developed by Robert Gunning. It indicates the number of years of formal
education required to read and understand a passage of text. The Flesch Index, developed in 1940 by Dr. Rudolph Flesch, is another indicator of reading ease. The score returned is based
on a 100 point scale, with 100 being easiest to read. Scores between 90 and 100 are appropriate for 5th and 6th graders, while a college degree is considered necessary to understand text
with a score between 0 and 30. The Flesch-Kincaid Index is a refinement to the Flesch Index that tries to relate the score to a U.S. grade level. For example, text with a Flesch-Kincaid
score of 10.1 would be considered suitable for someone with a 10th grade or higher reading level. The Complexity calculations indicate the complexity of the words and sentence structure
in the text of a book. A word is considered "complex" if it has three or more syllables.
