Readability of Cancer Pamphlets
A study was conducted in order to find out whether pamphlets containing information for cancer patients are written at a level that the cancer patients can understand.
Tests were administered to measure the reading levels of 63 cancer patients, and the readability levels of 30 cancer pamphlets were evaluated based on such factors as the lengths of the sentences and the number of polysyllabic words.
Both the reading and readability levels correspond to grade levels, but patients’ reading levels of less than grade 3 and above grade 12 cannot be determined exactly. (Source: Short, Moriarty, and Cooly. (1995). “Readability of Educational Materials for Cancer Patients.” Journal of Statistics Education, v.3, n.2)
The following tables indicate the number of patients at each reading level and the number of pamphlets at each readability level.
- Note that the data are presented in a grouped form; the actual readability data, for example, are: 6 6 6 7 7 7 8 8 8 8 8 8 8 8 9 9 9 9, etc.
