Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. Children who suffer from untreated sleep apnea often have behavioral problems including hyperactivity, inattention, and aggression.
Suppose researchers at a sleep clinic are interested in the effect of a surgical treatment for sleep apnea on hyperactive behavior. They study 11 children without sleep apnea, 11 children with untreated sleep apnea, and 11 children who have been surgically treated for sleep apnea. Hyperactivity is measured using the Conners Rating Scales.
