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 lurking variable that may lead to confounding with the effects of small classes. Explain how confounding might occur.

I think students in a smaller classroom is able to get more individual attention then those in a bigger class.

Ex class A as 10 student Class B has 20

assuming there is one teacher in both classes, the teacher is able to give more attention to all the 10 kids, but not the 20.
