Suppose you are reading a study that should report a Pearson correlation because its variables are both scale data, but instead, it reports a Spearman correlation. Why might the researchers have done this?
A researcher is examining the link between pet ownership (three categories: no pet, dog, cat) and depression (two categories: Yes, No). In the Results section of her publication, you read the information: ?2(2, N = 800) = 6.72, p < .05.
Ans: There has been some violation of the assumptions for the Pearson correlation. When this happens, we turn to nonparametric tools, such as the Spearman correlation, to make sense of our data.
