Visual Analysis within Behavior Analysis

The analysis of graphic data in single case designs serves as the primary means for judging the significance of results. Many sources both within and outside behavior analysis provide guidelines for the visual analysis of graphed time series data. Following a compiling of the rules of visual analysis, the current talk will focus on the results of a survey of within condition analyses within behavior analytic journals. The results found a majority of articles used very few within condition analytic tactics. When used, researchers tended to rely on level rather than trend, variability, or number of data points per condition. The discussion covers adherence to graphical analysis guidelines and the subjective nature of qualitative descriptors.
