Is honey a cough remedy? Refer to the Archives of Pediatrics and Adolescent Medicine (December 2007) study of honey as a children’s cough remedy, Exercise 8.23 (p. 453). Recall that 70 children who were ill with an upper respiratory tract infection were given either a dosage of dextromethorphan (DM)—an over-the-counter cough medicine—or a similar dose of honey. Parents then rated their children’s cough symptoms, and the improvement in total cough symptoms score was determined for each child. The data (improvement scores) are reproduced in the accompanying table. The researchers concluded that “honey may be a preferable treatment for the cough and sleep difficulty associated with childhood upper respiratory tract infection.” Use the nonparametric method presented in this section to analyze the data (use a = .05). Do you agree with the researchers?
