WGU C784 Applied Healthcare Statistics – Objective
Assessment 1 Exam Questions and Answers with Detailed
Rationales 2026 | Verified | 100% Accurate
Question 1
The nurse is documenting the number of patients admitted to each unit in a hospital. What type of data
is this?
- A) Continuous
- B) Discrete
- C) Qualitative
- D) Ordinal
Answer: B) Discrete
Explanation: Discrete data has distinct, separate values and can be counted (e.g., number of patients).
Continuous data is measured and can include fractions (e.g., height, weight). Qualitative data describes
qualities or categories. Ordinal data has ordered categories but unequal intervals.
Question 2
A patient’s blood pressure reading is 120/80 mmHg. Which type of data is this?
- A) Discrete
- B) Categorical
- C) Continuous
- D) Nominal
,Answer: C) Continuous
Explanation: Continuous data can take any value within a range and is measured (not counted). Blood
pressure can be 120.5 mmHg, 121.3 mmHg, etc., so it is continuous.
Question 3
Given the numbers 3.3, –2.3, –16, and 25, what are the square roots of the whole number present in the
set?
- A) ± 2.3
- B) ± 3.3
- C) ± 4
- D) ± 5
Answer: D) ± 5
Explanation: The whole numbers in the set are –16 and 25. The square roots of 25 are +5 and –5
because 5 × 5 = 25 and (–5) × (–5) = 25.
Question 4
Given the numbers 10, 2.5, –4, –4.5, and 5, what is the sum when adding together only the whole
numbers?
- A) 5.5
- B) 11
- C) 12.5
,- D) 15
Answer: D) 15
Explanation: The whole numbers in the list are 10, –4, and 5. Adding them: 10 + (–4) = 6; 6 + 5 = 15.
Question 5
A document shows that 0.5 of a medication is administered. What is this decimal value expressed as a
fraction in simplest form?
- A) 1/5
- B) 1/2
- C) 3/5
- D) 2/3
Answer: B) 1/2
Explanation: 0.5 is read as five-tenths, which simplifies to 1/2 when divided by the greatest common
factor (5/10 = 1/2).
Question 6
During a study, a patient’s energy level is described as “high,” “medium,” or “low.” What type of data is
this?
- A) Ratio
- B) Continuous
- C) Ordinal
- D) Interval
, Answer: C) Ordinal
Explanation: Ordinal data has categories with a natural order (e.g., high, medium, low), but the intervals
between categories are not necessarily equal.
Question 7
Five patients have ages 23, 34, 34, 45, and 56 years. What is the median age?
- A) 23
- B) 34
- C) 38.4
- D) 56
Answer: B) 34
Explanation: The median is the middle value when numbers are ordered. In ascending order, the third
value is 34.
Question 8
Using the order of operations, what is the result of 5 × (30 − 27)² + 4?
- A) 34
- B) 49
