A group of NPs at a clinic want to determine which of two medications produces better outcomes for patients. Obviously type of medication is measured at the nominal level (e.g. Med-A and Med-B). But their outcome variable is years of survival after the medication is started. They could measure the years directly, or categorize them as follows: 1 to 5 years, 6 to 10 years, 11 to 15 years, 16 years or more. Why is it likely to be better to use the actual years of survival rather than the categorized years? Question 27 options: a) It is just easier to record actual years than categorize them. b) Categories are harder to measure than years. c) The power of the statistics they can use to analyze their data is greater with the actual numbers. d) There is no actual advantage for either measure, and thus it is not better to measure the actual number of years rather than using categories
