Which characteristic of Studentized residuals indicate potential outliers?
Studentized residuals are used to identify potential outliers in a data set. Residuals that are less than negative two or greater than two are considered significant as they indicate that those data points deviate substantially from the predicted values. This means that studentized residuals with absolute values greater than 2 are potential outliers.
Answer should be B on a two tailed test.
Technically, you are right. I am also confused with the sas contents presenting that In general, studentized residuals that have an absolute value less than 2.0 could have easily occurred by chance. that`s why answer might be C.
Should be B, see the link I posted below.
