Question : Carryover Effects
CORRECT ANSWER : -Refers for an effect of being tested in
one state on participants' behavior in later situations- May occur in a within-subject trial when the effect of a particular level of the self-independent variable persists even after the treatment finishes

Question : Amanda is an RBT at an ABA clinic. She is working
with her client, Jerrell, to decrease aggressive behaviors (i.e., biting others). She has collected data for the frequency of Jerrell's bites for three weeks.

17Week 3: 16, 7, 9, 3, 0
CORRECT ANSWER : Mean= 12, Median=11, Mode=7,22

elementary school. Dr. Jones collected data throughout the duration of the school year across two elementary schools. In school A, all k-6 classrooms used the Good Behavior Game. In School B, no classrooms used the Good Behavior Game. At the end of the school year, Dr. Jones concluded that the Good Behavior Game had no impact on student disruptive behavior,
when in fact it had. This is an example of:
CORRECT ANSWER : A Type 2 Error
