Parametric analysis is used to evaluate a range of values for an intervention (independent variable).  For example, if you were determining the range of values for “time out” that are most effective.  You would conduct a parametric analysis using 1 minute, 5 minutes, 10 minutes, and so on.  Parametric analysis can be thought of as the quest for “how much” intervention is needed to be effective.

Visual analysis is used to look at graphed data.

Component analysis attempts to determine which part of an independent variable is responsible for behavior change.  Component analysis can be thought of as “which part” of the intervention was effective.
