1. Threats to internal validity include - CORRECT ANSWERS.✔️✔️Testing, maturation, procedural
infidelity
2. Events that occur during the experiment but that are not related to planned procedural changes
that may influence the outcomes. - CORRECT ANSWERS.✔️✔️History
3. Changes in behavior due to the passage of time - CORRECT ANSWERS.✔️✔️Maturation
4. Occurs when participants need to respond to the same test repeatedly during a baseline or
probe condition, whcih influences responding - CORRECT ANSWERS.✔️✔T️ esting
5. Threats related to the measurement system, and are of concern because of repeated
measurement by human observers who may make errors - CORRECT
ANSWERS.✔️✔️Instrumentation
6. Inconsistent implementation of the experimental condition - CORRECT
ANSWERS.✔️✔️Procedural infidelity
7. The loss of participant's behavior is influenced by more than one planned intervention during
the course of a study - CORRECT ANSWERS.✔️✔️Multiple treatment interference
8. A type of data instability that refers to a repeated and predictable pattern in the data series over
time - CORRECT ANSWERS.✔️✔️cyclical variability
9. Carryover effects: - CORRECT ANSWERS.✔️✔️

11. 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. Calculate the mean, median, and mode of the following data set (round to the nearest
whole number):
12. Week 1: 22, 31, 20, 32, 32
13. Week 2: 7, 8, 13, 31, 17
14. Week 3: 16, 5, 9, 12, 15 - CORRECT ANSWERS.✔️✔️Mean = 18, median =16, Mode =31,32
15. Dr. Jones wanted to know if the use of the Good Behavior Game decreased rates of disruptive
behaviors in an 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 shouted, "Eureka! The Good Behavior Game works," when in fact it had
no impact on student disruptive behavior. This is an example of: - CORRECT ANSWERS.✔️✔️A
type II error
16. The primary purpose of the method section is to: - CORRECT ANSWERS.✔️✔️Both A and B
17. Detail the plan of study being proposed.
18. Provide a sufficiently detailed description of the study so a trained researcher can implement
the study as intended with no additional guidance.
19. Which of the following is true about single-case research design? - CORRECT
ANSWERS.✔️✔️Most studies include more than one participant
20. These graphs demonstrate which of the following - CORRECT ANSWERS.✔️✔️inter-subject
replication with a multiple baseline design across behaviors
21. These data show (q10) - CORRECT ANSWERS.✔️✔️A change in variability
22. Which of the following is a limitation of using statistical significance to differentiate between
meaningful and trivial change? - CORRECT ANSWERS.✔️✔️The rejection of the null hypothesis is
more decisive in larger sample sizes.
23. Large enough sample sizes will always show a significant difference between populations
24. Statistical analysis may fail to reject the null hypothesis in small sample sizes
