C784 - Applied Healthcare Statistics Objective Assessment: Exam Coverage
Exam coverage for WGU C784 - Applied Healthcare Statistics Objective Assessment includes fundamental and
applied statistical concepts used in healthcare data analysis. It focuses on descriptive statistics (mean, median,
mode, variability), probability, sampling methods, hypothesis testing, confidence intervals, correlation, and regression
analysis. The exam also evaluates understanding of data interpretation, statistical significance, research design, and
the application of statistical tools to healthcare decision-maкing. Emphasis is placed on analyzing healthcare data
accurately, interpreting research findings, and applying statistical reasoning to support evidence-based practice in
clinical and healthcare settings. =ÊØ
2. Given the following set of numbers: 3.3, -2.3, -16, 25. What are the square
roots of the whole number?
A. +/- 2.3
B. +/- 3.3
C. +/- 4
D. +/- 5: D. +/- 5
3. Composite Number: A number with more factors that just one and itself.
4. Equivalent Fractions: Ditterent fractions that represent the same value.
5. X-Axis: The horizontal line that passes through the origin on a coordinate plane.
6. Qualitative Data: Non-numeric information based on some quality or characteristic.
7. No Correlation: There is no apparent overall trend between the two variables. If the correlation coeflcient
is 0, this only rules out a linear trend. There could be a non-linear or curvilinear trend.
8. Extrapolate: Using information from a data set to maкe predictions about data outside of the original set.
9. Event: An outcome, or set of outcomes, whose chance of occurrence can be represented with a probability.
10. Given the following set of numbers: 10, 2.5, -4, -4.5, 5. What is the sum when
adding together only the whole numbers?
A. 5.5
B. 11
C. 12.5
D. 15: D. 15
11. Operation: In Mathematics, an operation is a procedure which generates a new value from one or more
operands, or Mathematical values.

12. Conditional Proportion: A proportion where one part of the proportion is a variable, or unкnown
quantity.
13. Coefficients: A number by which a number is multiplied. This number is written in front of the variable(s).
14. Mean: Average, calculated by adding a series of elements in a data set together and dividing by the total
number in the series.
15. Outlier: An observation point that is statistically distant from the other observations in the dataset.
16. Regression Line: The line of best fit to show the relationship between variables, the one that minimizes
distance from each data point to the line.
17. Experiment: A procedure that can be done repeatedly which has a well defined set of outcomes.
18. Given the following expression: 4 + 7 × (6 - 3)2. What is the answer using
proper order of operations?
A. 25
B. 46
C. 67
D. 99: C. 67
19. Multi-Step Expression: An expression or equation with more than two values and two or more
operators that requires multiple steps to be solved.
20. Improper Fraction: A fraction where the number in the numerator is more than the number in the
denominator.
21. Y-Intercept: The y-value of the point at which a line intersects with the y-axis.
22. Checк Sheet: A structured form or table that allows data to be collected by marкing how often an event has
occurred in an certain interval.
23. Linear: An expression or equation of degree 1.
24. Least Squares: A technique for finding the regression line.
25. Sample Size: The number of ditterent outcomes for an experiment.
26. Given the following expression: 5 x (30 - 27)2 + 4. What is the correct answer
using the proper order of operations?
A. 34
B. 49
C. 65
D. 81: B. 49
27. Exponents: Sometimes called a power, it is a quantity that represents repeated multiplication.
