This error repeats itself - Exact answerSystematic Error - Skewed results
Observation points that are distant from other observations. - Exact
answerOutliers Note: Can be included or excluded in analysis (causes
skewness)
Types of Bias: Bias that occurs from not selecting a random sample -
Exact answerMeasurement bias

beneficial if selected. - Exact answerConscious bias (key word: benefit)
Consistent and repeatable data - Exact answerReliable
Resulting from accurate measurements - Exact answerValid data
If a responder lies on their survey, this creates what type of bias? - Exact
answerInformation
Sorting your spreadsheet can expose these errors by moving them to the
very top or the very bottom of the column - Exact answerOmission or Out-
of-Range

Which form of analytics is this? - Exact answerDescriptive: We are only
describing the past. No future predictions are made.
