Practice Test Bank: Fundamentals of Statistics for Nursing Research
1. Which type of research uses numerical data and statistical analysis?
A. Qualitative
B. Phenomenological
C. Quantitative
D. Ethnographic
,Correct Answer: C
Rationale: Quantitative research focuses on measurable, numerical data
and relies on statistical analysis to answer research questions and test
hypotheses .
2. Which level of measurement allows for ranking but does not have
equal intervals?
A. Nominal
B. Ordinal
C. Interval
D. Ratio
Correct Answer: B
Rationale: Ordinal data can be ranked (e.g., mild, moderate, severe pain)
but the intervals between the ranks are not equal or measurable, making
them distinct from interval or ratio data .
3. Which statistic represents the average value of a data set?
A. Mode
B. Median
C. Mean
D. Range
Correct Answer: C
, Rationale: The mean is the arithmetic average, calculated by summing
all values in a data set and dividing by the total number of observations .
4. Which measure of central tendency is most affected by extreme values
or outliers?
A. Median
B. Mode
C. Mean
D. Range
Correct Answer: C
Rationale: The mean is sensitive to extreme values. Outliers can
significantly pull the mean higher or lower, which is why the median is
often reported for skewed data .
5. What does a p-value indicate?
A. The sample size of the study
B. The probability that the results occurred by chance
C. The strength of a correlation
D. The validity of the study
Correct Answer: B
Rationale: A p-value represents the probability that the observed results
occurred by random chance, assuming the null hypothesis is true .
