ANSWER: It should be reported in a psychological journal using this formate of the APA style.
F(3, 26) = 2.91, P < .05
Explanation: APA which means American Psychological Association, has a style of reporting an experimental results in a their psychological journal.
To report the result of a one way ANOVA, one should be subtracted from the level of the independent variable, and the number of the levels should be subtracted from the number of subject in each group. The function of the values gotten is always equal to the result obtained at F. Since the alpha level is 0.05 that means P is less than 0.05.
30 - 4 = 26
4 - 1 = 3
Therefore;
F(3, 26) = 2.91
P < 0.05.
