WGU C207 Data Driven Decision Making Assessment
Study Exam with Questions and Verified Answers
1. Frame the Problem, Solving the Problem and Communicating Results are
part of which decision making model?: Davenport-Kim three-stage model
2. In which stage of the Davenport-Kim model is problem recognition?: Fram-ing
the problem
3. In which stage of the Davenport-Kim model is data collection?: Solving the
problem
4. What is a key reason we study statistics?: To make informed decisions
5. Visually presenting the data assists in which stage of the Davenport-Kim
model?: Communicating the results
6. When does research fail to produce reliable results?: Poor research validity
7. What are the two major issues surrounding research standards?: Best prac-
tices and ethics
8. In order to be a statistically valid sample, the sample must be:: The appro-
priate size and random
9. Not selecting a random sample is what type of bias?: Measurement
,10. Not selecting a right sized sample is what type of bias?: Measurement
11. Research best practices eliminate...: Bias
12. Outliers create this type of error: Out-of Range
13. Unpredictable error: Random Error - No correlation
14. Error may occur from missing data. (Example: Space not filled in): OmissionError
- Distorted results
15. This error repeats itself: Systematic Error - Skewed results
16. Observation points that are distant from other observations.: Outliers Note:
Can be included or excluded in analysis (causes skewness)
17. Types of Bias: Bias that occurs from not selecting a random sample: Mea-
surement bias
18. Types of Bias: Bias introduced because respondents believe it will be
beneficial if selected.: Conscious bias (key word: benefit)
19. Consistent and repeatable data: Reliable
20. Resulting from accurate measurements: Valid data
21. If a responder lies on their survey, this creates what type of bias?: Informa-tion
22. Sorting your spreadsheet can expose these errors by moving them to thevery
top or the very bottom of the column: Omission or Out-of-Range
, 23. An error that will fix itself over time: Random
24. An error that will not fix itself. You must do something: Systematic
25. Cleaning and organizing data: Data Management
26. Are the following variable quantitative or qualitative? Personality type,
social class, or communication style: Qualitative
