PART 1: UNDERSTANDING STATISTICAL
METHODS (Questions 1-100)
1
, Section 1: Identifying Levels of Measurement (Q1-
20)
Q1. 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) Interval
- C) Nominal
- D) Ratio
Answer: C) Nominal
Rationale: Blood type is a categorical variable with
no inherent order or ranking; categories are mutually
exclusive and labels only, which defines nominal-
level measurement .

,Q2. 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
Answer: B) Ordinal
Rationale: NYHA classification represents rank-
ordered categories with unequal intervals between
classes, which is the defining characteristic of
ordinal-level measurement .
3
, Q3. 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
Answer: C) Interval
Rationale: Temperature in Celsius has equal
intervals between values but lacks a true zero point
(0°C does not indicate absence of temperature),
making it interval-level data .
Q4. 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
