Variability
On a line graph, the degree to which the data points bounce around the data path.
Task List Reference: C-11
Interpret graphed data.
Test your ABA Terminology ➠ Fundamental Properties of Behavior Change
Test your ability to interpret graphed data with PTB co-founder Dana Meller. Here she explains the three fundamental properties of behavior change, focusing on one specific property akin to an average or median. Included are descriptions of level, trend, variability, and the y-axis.
Refer to BCBA® Task List (5th ed.) Section C-11: Interpret graphed data.

Level
On a line graph, the degree to which the data points on the y-axis converge, established by calculating the mean or median of the graphed data points.
Breaking Down a Mock BCBA® Exam Question: Understanding Equal-Interval Graphs & Logarithmic Scales
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.
