Question
What is the null hypothesis in the Mann Whitney U test?The mean rating of two datasets are equal.The frequency of two datasets are equal.The frequency of two datasets are not equal.The mean ratings of two datasets are not equal.
Solution
The null hypothesis in the Mann Whitney U test is that the distributions of two populations are equal. In other words, there is no difference between the two populations being compared. This can be interpreted as the mean ranks of the two datasets being equal. Therefore, the correct answer is "The mean rating of two datasets are equal."
