C784 MATH 1100 Applied Healthcare Statistics
(NI)
Objective Assessment Review (Qns & Ans)
2025
1. What is the primary purpose of descriptive statistics in
healthcare?
a. Predicting future trends
b. Summarizing and organizing data ( Correct ANS )
c. Conducting hypothesis testing
d. Establishing cause-and-effect relationships
Rationale: Descriptive statistics help summarize and present
data in a meaningful format, enabling understanding of data
trends.
2. Which measure represents the middle value in a dataset when
arranged in ascending order?
©2025
, a. Mean
b. Median ( Correct ANS )
c. Mode
d. Standard deviation
Rationale: The median is the central value that separates a
dataset into two equal halves.
3. In a healthcare study, what is the independent variable
typically associated with?
a. The variable being measured
b. The variable being manipulated ( Correct ANS )
c. The outcome of the study
d. The sample size of the study
Rationale: The independent variable is controlled or
manipulated to observe its effect on the dependent variable.
4. Which type of data is most suitable for calculating a Pearson
correlation coefficient?
a. Categorical
b. Ordinal
c. Interval or ratio ( Correct ANS )
d. Nominal
©2025
, Rationale: Pearson correlation measures the strength and
direction of relationships between continuous interval or ratio
data.

5. A __________ variable represents categories or groups that
have no inherent order or ranking.
ANS: Nominal
Rationale: Nominal variables include categories like gender
or blood type, with no rank or order.
6. In healthcare statistics, the __________ quantifies the amount
of variation or dispersion in a dataset.
ANS: Standard deviation
Rationale: Standard deviation provides insight into how
spread out the data points are around the mean.
7. The __________ hypothesis states that there is no significant
difference or relationship between variables.
ANS: Null
