I see, so it's likely that normality assumption is violated in this case.

Constant variance? Normality? These statistical terms sound like they're from a different planet! I'll just go with option D and hope for the best.

That could also be a factor, but the probability value is a stronger indicator.

I agree with Raymon, the Prob > F is less than .0001.

The Prob > F being less than 0.0001 is a dead giveaway that the normality assumption has been violated. Option A is the way to go, my friends.

Haha, these ANOVA assumptions are like a game of 'guess the right answer'! I'm going with option D, constant variance, because the box plots don't look very consistent across the campaigns.

The interquartile ranges are different in the box plots, so I think the assumption of constant variance has been violated. Option D seems to be the correct answer here.

The box plot clearly shows the difference in interquartile ranges, making constant variance assumption invalid.
