In this paper, two methods of sequential analysis are applied to hypothetical observational data. The first method employs the conventional "conditional probability" approach, illustrated using the GSEQ program (Bakeman & Quera, 1995). In order to overcome some of the difficulties associated with the conditional probability approach, the second method employs a new "normalized and pooled" approach. Essentially, by normalizing periods of time preceding, during, and following each occurrence of a nominated "given" behavior, the proportion of time units devoted to a "target" behavior can be estimated and then pooled across all occurrences of the given behavior. A summary diagram representing the likelihood that the target behavior precedes, occurs concurrently with, and follows the given behavior can then be constructed. Elements of this summary diagram can also be quantified. Given the graphical nature of the output, and its ease of use, the normalized and pooled approach may help to promote the use of sequential analysis in applied settings.
