QUESTION:

Effects of class size Do smaller classes in elementary school really benefit students in areas such as scores on standardized tests, staying in school, and going on to college? We might do an observational study that compares students who happened to be in smaller and larger classes in their early school years. Identify a variable that may lead to confounding with the effects of small classes. Explain how confounding might occur.
