Document Summary
1. descriptive: characterizes the level of behavior existing before intervention. 2. predictive: predicts the future level of the target behavior in the absence of the iv or if the iv has no effect; serves as a criterion to evaluate whether the intervention produces change. 3. phase change line: indicates that something new started- move it to an ab design; movement in the analysis from one level or kind of independent variable to the next level or kind of independent variable. 4. characteristics of a data series to decide to use a phase change line: level, variability (or stability), and trend. 5. level: behavior is high/low enough that you will be able to detect a change if one occurs. 6. variability (or stability): levels of behavior do not vary greatly from one measurement to the next. 7. trend: the behavior is not already changing in the direction predicted for treatment. 9. irreversibility and its application to experimental designs: sometimes items can"t be reversed.
