Solution Manual for Statistics for Nursing Research A Workbook for Evidence-Based Practice 3rd Edition Susan Grove Daisha In Table 1, identify the level of measurement for the current therapy variable. Provide a rationale for your answer. Answer: The current therapy variable was measured at the nominal level. These drug categories were probably developed to be exhaustive for this study and included the categories of drugs the subjects were receiving. However, the categories are not exclusive, since patients are usually on more than one category of these drugs to manage their health problems. The current therapies are not measured at the ordinal level because they cannot be rank ordered, since no drug category can be considered more or less benefi cial than another drug category (see Figure 1-1 ; Grove & Gray, 2019) . 2. What is the mode for the current therapy variable in this study? Provide a rationale for your answer. Answer: The mode for current therapy was blocker. A total of 100 (94%) of the cardiac patients were receiving this category of drug, which was the most common prescribed drug for this sample. 3. What statistics were conducted to describe the BMI of the cardiac patients in this sample? Discuss whether these analysis techniques were appropriate or inappropriate. Answer: BMI was described with a mean and standard deviation ( SD ). BMI measurement resulted in ratio-level data with continuous values and an absolute zero (S tone & Frazier, 2017) . Ratiolevel data should be analyzed with parametric statistics such as the mean and SD (G rove & Gray, 2017 ; Knapp, 2017 ). 4. Researchers used the following item to measure registered nurses’ (RNs) income in a study: What category identifi es your current income as an RN? a. Less than $50,000 b. $50,000 to 59,999 c. $60,000 to 69,999 d. $70,000 to 80,000 e. $80,000 or greater
