**Question description**

You as the primary researcher are interested in the possible effects of the drug Ritalin on the behavior of ADHD children. A group of children diagnosed with ADHD are randomly selected and taken for treatment to a behavioral-psychology clinic. The group of children is then randomly broken down into two groups, group A and group B. The two groups are then measured on an ADHS scale. Group A is given daily doses of Ritalin, while Group B is given a placebo. Both groups receive identical daily behavioral treatment at the clinic. Then six weeks later the children are reevaluated regarding their ADHD. At the end of this six week period, the pre-test and post-test scores for all the children are compared. •What kind of research is this? •Identify the IV(s) and DV(s) •Were all of the possible confounding variables controlled? If not, what other variables might the researcher have at least attempted to control? •Was the possibility of outside events contaminating the IV controlled? •Discuss the study's internal and external validity. •What type of statistical analysis would you propose? •If the differences are significant, what kinds of conclusions could you legitimately draw?
