A nurse researcher records participants' blood types (A, B, AB, O) in a study examining transfusion compatibility. What is the level of measurement for this variable? A. Ordinal B. Nominal C. Interval D. Ratio Correct Answer: B Rationale: Blood type is a categorical variable with no inherent order or ranking. Categories are mutually exclusive and represent labels only, which defines nominal-level measurement. Arithmetic operations cannot be performed on nominal data; only frequency counts and percentages are appropriate. ________________________________________ 2. In a cardiac study, patients are classified using the New York Heart Association (NYHA) Functional Classification: Class I (no symptoms), Class II (slight limitation), Class III (marked limitation), and Class IV (symptoms at rest). What level of measurement does this represent? A. Nominal B. Ordinal C. Interval D. Ratio Correct Answer: B Rationale: NYHA classification represents rank-ordered categories from mildest to most severe, but the intervals between classes are not equal. The difference between Class I and Class II is not necessarily equivalent to the difference between Class III and Class IV. This defines ordinal-level measurement . ________________________________________ 3. A researcher measures body temperature in degrees Celsius for patients post-surgery. What level of measurement is this variable? A. Nominal B. Ordinal C. Interval D. Ratio Correct Answer: C Rationale: Temperature in Celsius has equal intervals between values but lacks a true zero point (0°C does not indicate absence of temperature). Therefore, it is interval-level data. Ratio statements such as "20°C is twice as warm as 10°C" are not valid . ________________________________________ 4. A nurse researcher records the time (in minutes) it takes for patients to complete a 6-minute walk test. What is the level of measurement? A. Nominal B. Ordinal C. Interval D. Ratio Correct Answer: D Rationale: Time in minutes has equal intervals and a true zero point (0 minutes means no time elapsed), allowing meaningful ratios (e.g., 10 minutes is twice 5 minutes). This defines ratio-level measurement. ________________________________________ 5. A study uses a multi-item Likert scale (1 = Strongly Disagree to 5 = Strongly Agree) to measure nurses' attitudes toward evidence-based practice. When treated as a total score for parametric analysis, this variable is considered: A. Nominal B. Ordinal C. Interval D. Ratio Correct Answer: C Rationale: Total scores from multi-item Likert scales are typically treated as interval-level data in nursing research to allow parametric statistical analysis. The summed scores approximate equal intervals, and while no true zero exists, the composite score functions as a continuous measure. ________________________________________ 6. A researcher records participants' marital status as single, married, divorced, or widowed. Which statistical technique is most appropriate for analyzing this variable? A. Mean and standard deviation B. Frequency distribution and percentages C. Pearson correlation D. Paired t-test Correct Answer: B Rationale: Nominal-level data such as marital status can only be analyzed using nonparametric descriptive statistics like frequencies and percentages. Means, correlations, and t-tests require at least interval-level measurement. ________________________________________ 7. A study categorizes annual household income as: $25,000, $25,000–$49,999, $50,000–$74,999, and ≥$75,000. What is the level of measurement? A. Nominal B. Ordinal C. Interval D. Ratio Correct Answer: B Rationale: Categorical income data are ordinal because categories can be rank-ordered from lowest to highest, but the intervals between categories are not equal, and the true dollar amount is unknown within each category. Continuous income measured in dollars would be ratio-level.
