Hello,

How do I properly report an ANOVA followed by Dunnett's MCT in APA format?

Below is the report minitab generates for Effects of Dose on a specific analyte. From what I have gathered, I should report this as:

A significant difference was found between Dosage level and Analytle A, F(4,10) = 10.63, p=.001. Dunnett's MCT was used to determine that Dose 3 was signficantly lower (M=4.02, 95% CI [-0.132, -0.041] than the Control condition (M=4.10).

Does this seem correct?
