Readability Measures

Readability is a measure of the relative difficulty of reading written text, usually reported as a numerical value keyed either to a grade level or to a point scale. It is usually calculated using a mathematical formula that considers features of a given text, such as word length, incidence of multisyllabic words, and sentence length.
