Frame the Problem, Solving the Problem and Communicating Results are part of which
decision making model? - ansWer-Davenport-Kim three-stage model
In which stage of the Davenport-Kim model is problem recognition? - ansWer-Framing
the problem
In which stage of the Davenport-Kim model is data collection? - ansWer-Solving the
problem
What is a key reason we study statistics? - ansWer-To make informed decisions
Visually presenting the data assists in which stage of the Davenport-Kim model? -
ansWer-Communicating the results
When does research fail to produce reliable results? - ansWer-Poor research validity
What are the two major issues surrounding research standards? - ansWer-Best
practices and ethics
In order to be a statistically valid sample, the sample must be: - ansWer-The
appropriate size and random
Not selecting a random sample is what type of bias? - ansWer-Measurement
,Not selecting a right sized sample is what type of bias? - ansWer-Measurement
Research best practices eliminate... - ansWer-Bias
Outliers create this type of error - ansWer-Out-of Range
Unpredictable error - ansWer-Random Error - No correlation
Error may occur from missing data. (Example: Space not filled in) - ansWer-Omission
Error - Distorted results
This error repeats itself - ansWer-Systematic Error - Skewed results
Observation points that are distant from other observations. - ansWer-Outliers Note:
Can be included or excluded in analysis (causes skewness)
Types of Bias: Bias that occurs from not selecting a random sample - ansWer-
Measurement bias
Types of Bias: Bias introduced because respondents believe it will be beneficial if
selected. - ansWer-Conscious bias (key word: benefit)
Consistent and repeatable data - ansWer-Reliable
Resulting from accurate measurements - ansWer-Valid data
If a responder lies on their survey, this creates what type of bias? - ansWer-Information
Sorting your spreadsheet can expose these errors by moving them to the very top or the
very bottom of the column - ansWer-Omission or Out-of-Range
, An error that will fix itself over time - ansWer-Random
An error that will not fix itself. You must do something - ansWer-Systematic
Cleaning and organizing data - ansWer-Data Management
Are the following variable quantitative or qualitative? Personality type, social class, or
communication style - ansWer-Qualitative
A study used when you a conditions can't be controlled - ansWer-Observational study
Observes people going forward in time from the time of their entry into the study. -
ansWer-Cohort Study
What are the three elements of an experimental study? - ansWer-Unit, Treatment,
Response
Accurately measures what it is intended to measure - ansWer-Valid data
________ an experimental study prevents bias. - ansWer-Blinding
Neither the treatment allocator nor the participant knows in which group the participant
is contributing. (Who is getting the real drug?) - ansWer-Double blind study
The participants are not told if they are in the treatment group or control group -
ansWer-Blind study
Describes characteristics of a dataset. Mean, median, mode, variation, standard
deviation, range.... - ansWer-Descriptive analytics
