Is honey a cough remedy? Refer to the Archives of Pediatrics and Adolescent Medicine (Dec. 2007) study of honey as a remedy for coughing, Exercise.Recall that coughing improvement scores were recorded for children in three groups: the over-the-counter cough medicine dosage (DM) group, the honey dosage group, and the control (no medicine) group. The data are saved in the HONEYCOUGH file.
a. For each group, construct a box plot of the improvement scores.
b. How do the median improvement scores compare for the three groups?
c. How does the variability in improvement scores compare for the three groups?
d. Do you detect any outliers in any of the three coughing improvement score distributions?
Is honey a cough remedy? Refer to the Archives of Pediatrics and Adolescent Medicine (Dec. 2007) study of honey as a remedy for coughing, Exercise.Recall that the 105 ill children in the sample were randomly divided into three groups: those who received a dosage of an over-the-counter cough medicine (DM), those who received a dosage of honey (H), and those who received no dosage (control group). The coughing improvement scores (saved in the HONEYCOUGH file) for the patients are reproduced in the next table.
a. Find the median improvement score for the honey dosage group.
b. Find the median improvement score for the DM dosage group.
c. Find the median improvement score for the control group.
d. Based on the results, parts a–c , what conclusions can pediatric researchers draw? (We show how to support these conclusions with a measure of reliability in subsequent chapters.)
