FINAL OBJECTIVE ASSESSMENT 2024/2025( ACTUAL EXAMS
QUESTIONS AND ANSWER)WGU BSN APPROVED

A hospital is studying the effectiveness of two different heartburn treatments (Treatment A and
Treatment B) administered daily for a week. The results are measured after one week of treatment, by
placing a patient into one of two groups: heartburn subsided OR heartburn remained. Which numerical
measure could be used to analyze the data?



a. Correlation coefficient



b. Five-number summary



c. Median



d. Conditional percentages (correct answer)Correct. The answer is d. Both variables are categorical
(C→C) so we will use a two-way table. Therefore, our numerical measure will be conditional
percentages.



One of the challenges with young patients who suffer from acute asthma is delivering medication during
asthma attacks. Young patients often have difficulty managing traditional delivery methods, such as
inhalers. A study was done to determine whether using a nebulizer to deliver medication reduced the
duration of asthma attacks in pediatric patients. Patients were split into two groups. One group was
given traditional inhalers as a method to deliver medication during an attack. The other group was given
the nebulizer. The effectiveness of both delivery methods was measured by comparing the time it took
for an attack to subside. Which numerical measure would present the maximum and minimum amount
of time that it took for attacks to subside for both delivery methods?



a. Relative Frequency



b. Five-number Summary

, c. Correlation



d. Conditional percentages (correct answer)a. Relative Frequency



b. Five-number Summary



Correct. The answer is b. In this study one variable is categorical, and the other is quantitative (C→Q) .
The five-number summary will show five important statistical values: minimum, maximum, first quartile,
median, and third quartile. Therefore, the five-number summary would be the best choice to look at the
minimum and maximum values for both groups.



c. Correlation



d. Conditional percentages



An exercise physiologist was interested in how age affects reaction time. He sampled a population
ranging in age from 10 years old to 70 years old. Subjects were asked to complete a simple reaction time
test. The test consisted of subjects sitting in front of a computer, and clicking a mouse when the image of
a circle on a screen changed color from black to red. Subjects were asked to attempt the task 5 times.
The times from the five trials were averaged to give each subject an overall reaction time score. Which
numerical measure could be used to analyze the strength of the relationship between age and reaction
time?



a. Correlation coefficient



b. Conditional percentages



c. Mean



d. Five-number Summary (correct answer)a. Correlation coefficient
