The Fry Readability Graph is a tool used to assess the readability of a text. It helps educators and writers determine the appropriate reading level for their audience. The graph is created by plotting the average number of syllables per 100 words against the average number of sentences per 100 words. To use the Fry Readability Graph, one must select a passage of text, count the syllables and sentences, and then plot these values on the graph. The intersection point indicates the grade level of the text, making it easier to match reading materials with the skills of students or readers.
