### Have you heard of this?

This is the Flesch-Kincaid Readability Test. I was writing a document in Google Docs and checked the word count. Whoa Google Docs! The word count function not only checked the word count, gave me number of paragrphs, pages, spaces and sentences, but also applied not one, not two, but three readability assessments to my document: Flesch Readng Ease, Flesch-Kinkaid Grade Level, and an Automated Readability Index.

I pulled the following from Wikipedia, as referenced in the link above. But for the curious, my writers workshop literary exercise received an 82.50 on the Reading Ease assessment, and scored a 5th grade level on the other two tests......

In the Flesch Reading Ease test, higher scores indicate material that is easier to read; lower numbers mark passages that are more difficult to read. The formula for the Flesch Reading Ease Score (FRES) test is
$206.835 - 1.015 \left ( \frac{\mbox{total words}}{\mbox{total sentences}} \right ) - 84.6 \left ( \frac{\mbox{total syllables}}{\mbox{total words}} \right )$

Scores can be interpreted as shown in the table below.[1]
