Test your knowledge of ABA graphs with PTB co-founder Dana Meller as she reviews a BCBA® mock exam question about equal-interval graphs, exploring their unique properties. Included, Dana explains the concept of proportional values and highlights the graph(s) which operate on a logarithmic scale, offering a different perspective on changes in behavior.
Refer to BCBA® Task List (5th ed.) Sections C-10: Graph data to communicate relevant quantitative relations (e.g., equal-interval graphs, bar graphs, cumulative records); C-11: Interpret graphed data.
Test your Experimental Design skills with PTB co-founder Dana Meller as she reviews and breaks down a mock exam question about reversal design variations that display only one reversal. Included is a description of A-B-A, B-A-B, and A-B-A-B reversal designs.
Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).
Test your Experimental Design skills with a breakdown of a BCBA® mock exam question about the identification of a three-phase experimental design. Included is a detailed comparison between four different reversal designs: ABC reversal, ABA reversal, BAB reversal, and ABAB reversal. As a bonus, Dana also provides examples of instances in which each of the reversal designs would be implemented.
Refer to BCBA® Task List (5th ed.) Section D-5: Use single-subject experimental designs (e.g., reversal, multiple baseline, multielement, changing criterion).

Let’s review and break down a BCBA® mock exam question about measurement techniques in ABA, specifically percentage of opportunity. PTB co-founder Dana Meller explains how to calculate the percentage of opportunities where the behavior is exhibited and why this method is superior to rate, count, and interval recording in certain situations.
Refer to BCBA® Task List (5th ed.) Section C-3: Measure occurrence (e.g., count, frequency, rate, percentage).
