UPDATED QUESTIONS AND ANSWERS 100% VERIFIED EXAM
PREP
, Visually presenting the data assists in which stage of the Communicating the results
Davenport-Kim model?
When does research fail to produce reliable results? Poor research validity
What are the two major issues surrounding research Best practices and ethics
standards?
In order to be a statistically valid sample, the sample must be: The appropriate size and random
Not selecting a random sample is what type of bias? Measurement
Not selecting a right sized sample is what type of bias? Measurement
Research best practices eliminate... Bias
Outliers create this type of error Out-of Range
Unpredictable error Random Error - No correlation
Error may occur from missing data. (Example: Space not filled Omission Error - Distorted results
in)
This error repeats itself Systematic Error - Skewed results
Observation points that are distant from other observations. Outliers Note: Can be included or excluded in analysis (causes skewness)
Types of Bias: Bias that occurs from not selecting a random Measurement bias
sample
Types of Bias: Bias introduced because respondents believe it Conscious bias (key word: benefit)
will be beneficial if selected.
Consistent and repeatable data Reliable
Resulting from accurate measurements Valid data
