Suppose you are reading a study that should report an independent samples t test because its outcome variable is scale data, but instead, it reports a Mann-Whitney U test. 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 independent samples t test. When this happens, we turn to nonparametric tools, such as the Mann-Whitney U test, to make sense of our data.
