Jonathan heard a news report that eating a gluten-free diet makes a person more likely to have a positive
outlook on life. This sounded appealing, but he felt he should investigate the claim before drastically changing
his diet. Jonathan asked 100 people at his school whether they eat gluten-free and then determined whether
they are positive or negative people.
Jonathan found that there was no association between eating gluten-free and having a positive outlook.
