intervention during the course of a study - correct answer...✔✔Multiple treatment
interference

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
The primary purpose of the method section is to: - correct answer...✔✔Detail the plan
of study being proposed.

These data show which of the following: - correct answer...✔✔A change in variability
Which of the following is a limitation of using statistical significance to differentiate
between meaningful and trivial change? - correct answer...✔✔All of the above
Which of the following is a limitation of group design? - correct answer...✔✔All of the

Kacyn is a BCBA at an ABA Center. She is running a small social skills group with 6
children who have autism spectrum disorder. Kacyn is using the "Tough Kids Social
