Communicating Results are part of which de-
cision making model?
2. In which stage of the Davenport-Kim model Framing the problem
is problem recognition?
3. In which stage of the Davenport-Kim model Solving the problem
is data collection?
4. What is a key reason we study statistics? To make informed decisions
5. Visually presenting the data assists in which Communicating the results
stage of the Davenport-Kim model?
6. When does research fail to produce reliable Poor research validity
results?
7. What are the two major issues surrounding Best practices and ethics
research standards?
8. In order to be a statistically valid sample, the The appropriate size and random
sample must be:
9. Not selecting a random sample is what type Measurement
of bias?
10. Not selecting a right sized sample is what Measurement
type of bias?
11. Research best practices eliminate... Bias
12. Outliers create this type of error Out-of Range

18. Types of Bias: Bias introduced because re- Conscious bias (key word: benefit)
spondents believe it will be beneficial if se-
lected.
19. Consistent and repeatable data Reliable
20. Resulting from accurate measurements Valid data
21. If a responder lies on their survey, this cre- Information
ates what type of bias?
22. Sorting your spreadsheet can expose these Omission or Out-of-Range
errors by moving them to the very top or the
very bottom of the column
23. An error that will fix itself over time Random
24. An error that will not fix itself. You must do Systematic
