Question: Norton Score for Elderly Orthopedic Patients

In their paper “A preliminary discriminant function analysis of elderly orthopedic patients who will or will not contract a pressure sore” in the International Journal of Nursing Studies (1980), Goldstone et al. Norton scores which measure mental condition, activity, mobility, and incontinence were reported for elderly orthopedic patients. Patients were classified into three groups: patients who did not develop pressure sores, patients who developed noticeable erythema, and patients who developed pressure sores. Do the data in the file Norton Scores.JMP provide evidence that the Norton scores for these three populations of elderly orthopedic patients differ?

a) Use an appropriate method to answer the question of interest. Summarize your
findings (5 pts.)

b) Using an appropriate multiple comparison strategy, compare the population Norton
scores of patients who did not develop sores to those that did develop sores. What is

your conclusion based upon this comparison? (4 pts.)
