### Reporting Mann Whitney U Test in APA

1. 1. Reporting Mann Whitney U Test in APA
2. 2. In this short tutorial you will see a problem that can be investigated using the Mann Whitney U Test.
3. 3. In this short tutorial you will see a problem that can be investigated using the Mann Whitney U Test. You will then see how the results of the analysis can be reported using APA style.
4. 4. Problem: 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?
5. 5. Problem: 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?

11. 11. Here is one general template for reporting a Mann Whitney U test:
12. 12. A Mann-Whitney test indicated that the [insert dependent variable] was greater for [insert level 1 of the independent variable] (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _.
13. 13. A Mann-Whitney test indicated that the [insert dependent variable] was greater for [insert level 1 of the independent variable] (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
14. 14. A Mann-Whitney test indicated that the [insert dependent variable] was greater for [insert level 1 of the independent variable] (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
15. 15. A Mann-Whitney test indicated that the slices of pizza eaten was greater for [insert level 1 of the independent variable] (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
16. 16. A Mann-Whitney test indicated that the slices of pizza eaten was greater for [insert level 1 of the independent variable] (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
17. 17. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = ___) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
18. 18. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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. This is the median for football players
19. 19. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for [insert level 2 of the independent variable] (Mdn = ___), U= _._, p = ._ _ _. 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.
20. 20. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for basketball players (Mdn = ___), U= _._, p = ._ _ _. 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.
21. 21. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for basketball players (Mdn = 5), U= _._, p = ._ _ _. This is the median for basketball players 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.
22. 22. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for basketball players (Mdn = 5), U= 67.5, p = ._ _ _. This U value is used to determine statistical significance. 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.
23. 23. A Mann-Whitney test indicated that the slices of pizza eaten was greater for football (Mdn = 9) than for basketball players (Mdn = 5), U= 67.5, p = .034. The statistical significance value meaning that if we were to replicate this study 1000 times, we would be wrong 34 times. 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.
24. 24. Here is our reported result:
25. 25. A Mann-Whitney test indicated that the slices of pizza eaten was significantly greater for football players (Mdn = 9) than for basketball players (Mdn = 5), U = 67.5, p = .034.
