Research best practices eliminate...
Bias
Outliers create this type of error
Out-of Ranġe
Unpredictable error
Random Error - No correlation
Error may occur from missinġ data. (Example: Space not filled in)
Omission Error - Distorted results
, 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 selectinġ a random sample
Measurement bias
Types of Bias: Bias introduced because respondents believe it will be beneficial if selected.
Conscious bias (key word: benefit)
