Rate
A derived measure of behavior that involves calculating the number of occurrences of a given response within a given period of time (e.g., number of mands per hour). Answers the… Read more
C. Measurement, Data Display, and Interpretation
Reliability
Measurement is trustworthy when the degree to which repeating a measurement procedure under the same conditions produces the same result.
Scale break
Specific marks on, or breaks in, the x-axis (i.e., horizontal axis) indicating the time periods during which data were not collected.
6th Edition TCO
Scatterplot
A chart and measurement system that displays patterns related to behavior and specific time and setting variables.
Split-middle line of progress
A line drawn on a line graph that represents the general direction of the data; used to visually analyze the overall trend of the graphed data.

Standard celeration chart
A standardized process for charting and analyzing how the rate of behavior changes over time.
Temporal extent
A measure of the duration of time that a behavior occurs from onset (i.e., start) to offset (i.e., end).
Temporal locus
When measurement refers to the point in time that the behavior occurs (latency, interresponse time).
Training duration
The predicted amount of training time needed for a client to achieve independence and mastery in program goals.
Trials to criterion
The specification of the number of response opportunities required to achieve a pre-specified level of performance criteria.
