Quizplus · Accepted Answer

An outlier is an observation that is significantly different from other observations in the data. It can be an extreme value for either the dependent or independent variable(s), and it can have a significant impact on the fit of the regression model. Therefore, it is important to identify and address outliers in regression analysis. Choice B "Influential" refers to observations that have a strong effect on the regression model fit, and this is different from an outlier. Choices C "Independent" and D "Dependent" refer to variables and are not relevant to identifying outliers in a regression analysis.
