How can outliers significantly impact the Pearson's correlation coefficient value?
- Outliers can decrease the Pearson's correlation coefficient value
- Outliers can distort the Pearson's correlation coefficient value
- Outliers can increase the Pearson's correlation coefficient value
- Outliers do not impact the Pearson's correlation coefficient value
Outliers can distort the Pearson's correlation coefficient value. Because Pearson's correlation measures the linear relationship between two variables, it is sensitive to outliers. An outlier can cause a high or low correlation value, providing a misleading view of the strength of the relationship between the variables.
