How to Report P-Value for Mann Whitney U Test in SPSS Output?
The third table shows test Statistics. We used Mann-Whitney U test statistics (53.000) and Asymp. Sig. (2-tailed) to reject or fail to reject the null hypothesis.
If p > 0.05, we fail to reject the null hypothesis.
If p < 0.05, we must reject the null hypothesis.
Since in our example, p = 0.173 > 0.05, we fail to reject the null hypothesis and conclude that there is no difference in the Math test score between males and females.
How to Interpret a Mann Whitney U Test Results in APA Style?
Mann-Whitney U test was conducted to determine whether there is a difference in Math test scores between males and females. The results indicate non-significant difference between groups, [U = 53.00, p = .173]. In conclusion, We fail to reject the null hypothesis and conclude that there is no difference in the Math test score between males and females.
