Q2. Dr. King wanted to determine if a new treatment for ADHD was effective. He took four children with ADHD and measured their level of distraction on an interval level scale where higher scores mean a higher level of distraction. Next, each child received individual behavior therapy for three months, after which their levels of distraction were assessed again. Finally, to determine if the effects of treatment are long lasting, each child had his or her level of distraction measured again six months later. Fill in all missing values in the table. (Hint: start with the df column.) With a=.05, determine whether there are any significant differences among the conditions. If necessary, use the Tukey HSD posttest to determine which groups are significantly different. 71 Before the TL After the T3 6-month treatment follow-up 18 treatment Level of distraction 22 15 Source SS df MS Between treatments (31) Within treatments (WT) Between Subjects (3S) Error (E) Total 2. 60 F= 31.5 120 %3D 40 10
