Visual Analysis and Graphic Representation

This sequence guides undergraduate students through the technical and analytical skills required for visual analysis in Applied Behavior Analysis (ABA). Students progress from understanding graph components to constructing phase-change graphs, analyzing data trends (level, trend, variability), and writing objective progress reports based on visual evidence.

Graph Anatomy and Conventions

Students identify and label the essential components of a standard behavioral graph, including the x-axis, y-axis, phase change lines, and condition labels. They learn the standards for proportionality and clarity in ABA graphing.

Plotting Data and Phase Changes

Students practice converting raw behavior data into line graphs, focusing on the placement of data points and the correct implementation of phase change lines to distinguish baseline from intervention.

Analyzing Level Trend and Variability

Students learn to describe data paths using the professional vocabulary of Level, Trend, and Variability, developing the skills to objectively analyze behavioral patterns.

Interpreting Intervention Effects

Students evaluate intervention effectiveness by comparing baseline and intervention data, looking for immediacy of effect and calculating the percent of non-overlapping data (PND).

Reporting Progress and Data Narratives

Students translate visual data findings into professional written narratives for stakeholders, focusing on objective reporting and clinical precision.
