You are a researcher asked to study a new school-based intervention for children identified with attention related classroom difficulties. You would like to try an intervention where desks without chairs are utilized (i.e. children stand at their desks rather than sit still in chairs). Children from two different schools were recruited for this study. School A received the intervention treatment and School B was a control group with no treatment. Data was collected in September and December. This data is a child behavior checklist where higher numbers indicate more disorders.
