For this assignment, imagine that you are a researcher studying the connection between nutrition and children's achievement in school. Devise two studies to address the question: Does the nutritiousness of children's diet influence their grades? One study must be a cross-sectional experiment. One study must be a longitudinal naturalistic study. Describe each study in detail, including who the participants will be, what the protocol will be, and what the key variables will be. Compare and contrast the benefits and limitations of the two studies. Your assignment should be at least 400 words long (there is no maximum number of words).
