E For the next questions, I want you to consider that there is more than the existence or non-existence of correlation. You can have: Strong positive correlation Moderate positive correlation No correlation . Moderate negative correlation . Strong negative correlation Would inclusion of the outlier change the evidence regarding a linear correlation? O Yes. Including the outlier changes the evidence regarding a linear correlation. No. Including the outlier does not change the evidence regarding a linear correlation. For the next questions, I want you to consider that there is more than the existence or non-existence of correlation. You can have: Strong positive correlation . Moderate positive correlation No correlation. Moderate negative correlation Strong negative correlation Would inclusion of the outlier change the evidence regarding a linear correlation? Yes. Including the outlier changes the evidence regarding a linear correlation. O No. Including the outlier does not change the evidence regarding a linear correlation. Would you always draw the same conclusion to the above question with the addition of any outlier? O Yes, any outlier would result in the same conclusion. No, a different outlier in a different problem could lead to a different conclusion. Explain your answer to the second multiple-choice question. Edit Insert Formats - M BIUX, X A AT E - E- C &
