11. The Scheffe test Sleep apnea is a sleep disorder characterized by pauses in breathing during sleep. Children with sleep apnea have behavior problems, including hyperactivity, inattention, and aggression, as well as impaired learning and diminished academic performance. The removal of tonsils and adenoids that are enlarged, causing the obstruction of the airways, is one of the most common treatments for pediatric sleep apnea. A clinical psychologist studies the effects of tonsillectomy and adenoidectomy on aggressive behavior. Her quasi-experiment includes...

Hoekema et al. (A-3) studued the craniofacial morphology of patient diagnosed with obstructive sleep apnea syndrome (OSAS) in health male subjects. One of the demographic variables the researchers collected for all subjects was the Body Was INDEX (calculated by dividing weight in kg by the square of the patient's height's in cm). The following are the BMI values of 29 OSAS subjects. 33.57, 27.78, 40.81 ,38.34, 29.01, 47.78, 26.86, 54.33 ,28.99, 25.21, 30.49., 27.38 ,36.42 ,41.50 ,29.39 ,24.54 ,41.75, 44.68...
