A study compares different levels of vegetable consumption. One group of participants eats 2 servings per day, another eats 3 servings, another eats 4 servings, and the last group eats 5 servings per day. The study finds that only the group who ate 2 servings had lower antioxidant capacity than the group that consumed 5 servings per day. What should you look for?
- Make sure the omnibus effect is significant before looking at comparisons of individual groups.
- Nothing, clearly 5 servings is better than 2, that's just math.
- Family-wise error rates should be lower if they did not do a Bonferroni adjustment to the study.
- Eat more vegetables.
