My data set is small, with roughly 12 in each group (two groups). In addition, the distribution of the data is not normal. As a result, I ran a Mann-Whitney U test.

However, I also ran a one-way ANOVA and got the exact same results. Which test should I report and it is okay to say that I ran both with equal results but chose to report only the ANOVA?

Report the result from the Mann Whitney test that is the appropriate test irrespective of whether or not the F test gives you the same result.
