Ans: Sometimes, there is a general linear relationship between two variables, but one or a few outliers do not adhere to that pattern, so Pearson’s r is weakened. Other times, there is no general linear relationship between two variables, but one or a few outliers very strongly show a relationship, which strengthens Pearson’s r even though the relationship is not representative of the entire sample.
