patients’ likelihood of wearing orthodontic appliances, noting that orthodontics is perhaps the area of health care with the highest need for patient cooperation (Behenam & Pooya, 2007). Among their analyses, they compared students in primary school, junior high school, and high school. The data that follow have almost exactly the same means as the researchers found in their study, but with far smaller samples. The score for each student is his or her daily hours of wearing the orthodontic appliance. Did age of students impact how long they wore the orthodontic appliance for? Use alpha of .05. Primary school: 16, 13, 18 (M= 15.67, s= 2.52) Junior high school: 8, 13, 14, 12 (M= 11.75, s=2.63) High school: 20, 15, 16, 18 (M= 17.25, s= 2.22)
