Null Hypothesis for Mann Whitney U Test - Pizza Eating
- 1. Null-hypothesis for Mann Whitney U
- 2. To illustrate how to write a null-hypothesis for a Mann Whitney U test, let’s consider the following example:
- 3. Problem:
- 4. A pizza café owner wants to know who eats more slices of pizza: football or basketball players. With this information she will determine how much inventory she needs during football and basketball seasons. She asks you to set up a study, collect the data, run the analysis and interpret the results for her. After collecting the data you realize that there are some extreme outliers among basketball players that may skew the results. You determine to run a Mann Whitney U test. How would you state the null-hypothesis?
