A study of the effects of television violence on children was conducted at a local elementary school. Children were randomly selected from the fourth grade and shown a 10-minute cartoon with violent content. The children were then sent to the playground with other children.

Internal validity refers to the extent to which a study is free from confounding variables and thus can establish a causal relationship between the independent variable (television violence) and the dependent variable (aggressive behavior). In this study, the researchers randomly assigned children to groups and exposed them to different levels of television violence, which helps control for confounding variables and increase internal validity. Therefore, the study design makes it likely that the researcher's conclusion about the hypothesis has internal validity.
