Using your knowledge of single-subject designs, the ethical considerations that must be made in the selection of appropriate single-subject designs, and how to determine the effectiveness of interventions, discuss the following:

1. Explain the ethical considerations of using a reversal single-subject design when addressing aggressive or self-injurious behavior.

2. Differentiate baseline data and intervention data. How can baseline and intervention data allow you to determine intervention effectiveness?

3. Analyze the following line graph. Determine the level, trend, and/or variability of the data during baseline and intervention. Contrast the intervention data with the baseline data and determine the effectiveness of the intervention. Discuss the importance of analyzing trend in the determination of effectiveness.
