Line graph
A chart used to display the occurrence of behavior across specific time periods. Each data point shows the level of some quantifiable feature of the dependent variable in relation to… Read more
C. Measurement, Data Display, and Interpretation
Magnitude
The measurable dimension of a behavior’s strength, force, intensity, and/or severity.
6th Edition TCO
Mean level line
A horizontal line on a line graph established by calculating the average of the graphed data points; used to signify the degree to which data points converge on the y-axis.
6th Edition TCO
Measurement artifact
Data that represents an unwarranted and misleading picture of behavior because of how it was measured, typically a product of time-sampling, limiting measurement scales, or poorly scheduled measurement periods.
Measurement bias
When an observer’s measurement is influenced by an expectation or belief they hold rather than what actually occurred.
Median level line
A horizontal line on a line graph established by calculating the median of the graphed data points, used to signify the degree to which data points converge on the y-axis.
6th Edition TCO
Momentary time sampling
A time-sampling data collection method used to estimate the overall occurrence of a behavior by measuring the number of intervals during which the behavior occurs at the end of an
Observer drift
When observers collecting data have a shift/drift in how they interpret the operational definition of the target behavior that affects the validity of their data.
Observer reactivity
When an observer’s data collection or performance is influenced by the awareness that they are being monitored and evaluated.
Occurrence data
A measurement of behavior that represents its repeatability and countability.
6th Edition TCO
Operational definition
An objective, clear, and complete description of target behavior.

Partial interval recording
A time-sampling data collection method used to estimate the overall occurrence of a behavior by measuring the number of intervals during which the behavior occurs at any time within an
