Frame the Problem, Solving the Problem and Communicating Results are part of which
decision making model? -CORRECTANSWER Davenport-Kim three-stage model
In which stage of the Davenport-Kim model is problem recognition? -
CORRECTANSWER Framing the problem
In which stage of the Davenport-Kim model is data collection? -CORRECTANSWER
Solving the problem
What is a key reason we study statistics? -CORRECTANSWER To make informed
decisions
Visually presenting the data assists in which stage of the Davenport-Kim model? -
CORRECTANSWER Communicating the results
When does research fail to produce reliable results? -CORRECTANSWER Poor
research validity
,What are the two major issues surrounding research standards? -CORRECTANSWER
Best practices and ethics
In order to be a statistically valid sample, the sample must be: -CORRECTANSWER
The appropriate size and random
Not selecting a random sample is what type of bias? -CORRECTANSWER
Measurement
Not selecting a right sized sample is what type of bias? -CORRECTANSWER
Measurement
Research best practices eliminate... -CORRECTANSWER Bias
Outliers create this type of error -CORRECTANSWER Out-of Range
Unpredictable error -CORRECTANSWER Random Error - No correlation
Error may occur from missing data. (Example: Space not filled in) -CORRECTANSWER
Omission Error - Distorted results
This error repeats itself -CORRECTANSWER Systematic Error - Skewed results
, Observation points that are distant from other observations. -CORRECTANSWER
Outliers Note: Can be included or excluded in analysis (causes skewness)
Types of Bias: Bias that occurs from not selecting a random sample -
CORRECTANSWER Measurement bias
Types of Bias: Bias introduced because respondents believe it will be beneficial if
selected. -CORRECTANSWER Conscious bias (key word: benefit)
Consistent and repeatable data -CORRECTANSWER Reliable
Resulting from accurate measurements -CORRECTANSWER Valid data
If a responder lies on their survey, this creates what type of bias? -CORRECTANSWER
Information
Sorting your spreadsheet can expose these errors by moving them to the very top or the
very bottom of the column -CORRECTANSWER Omission or Out-of-Range
An error that will fix itself over time -CORRECTANSWER Random
An error that will not fix itself. You must do something -CORRECTANSWER Systematic
