Planned activity check
A time-sampling data collection method used to estimate the overall occurrence of behaviors of a group of individuals by measuring the number of intervals during which the behavior occurs at
Product measures
A measurement of a target behavior taken by measuring the lasting environmental changes produced by that behavior, rather than counting actual occurrences of the behavior. (E.g., test scores, completed chores,

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

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.

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).
