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.

When an observer’s measurement is influenced by an expectation or belief they hold rather than what actually occurred.
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.
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
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.
When an observer’s data collection or performance is influenced by the awareness that they are being monitored and evaluated.
A measurement of behavior that represents its repeatability and countability.
An objective, clear, and complete description of target behavior.
