Andrea Phelps and her colleagues studied the role of religious practice in the type of care received by terminally ill cancer patients. Most of the patients in the study were Christian. [Source: Andrea Phelps, et al. 2009. "Religious Coping and Use of Intensive Life-Prolonging Care Near Death in Patients with Advanced Cancer." Journal of the American Medical Association 301: 1140-47.] Suppose you conduct a similar study using a sample of patients whose religious traditions are more varied than those of the patients in the Phelps study. You collect a sample of 400 terminally ill patients and ask each whether they practice a religion and whether they are likely to seek intensive life-prolonging care. The most appropriate test to use to check whether there is a significant relationship between whether terminally ill patients practice a religion and whether they seek intensive life-prolonging care is a chi square. You know this is the case because the data are: Nominal Ratio
