For multiple responses investigators can measure interresponse time, rate or frequency, and celeration. Interresponse time is the temporal measure that reflects the time elapsing between two successive responses. Rate or frequency is a ratio of the number of times a behavior occurs over some period of time - typically referred to as responses per minute. It describes how often a behavior occurs averaged over a period of time. Finally, celeration is closely related to rate, and it represents changes in rate over time and to determine celeration you divide rate by time.

What are two different ways that rate can be calculated?

Rate is calculated by dividing the total count of responses by: (1) the total amount of time when responses were not occurring (i.e., total IRT), and (2) the total time when the behavior was observed (i.e., total session time or duration of observation).

You are working with a 4th grader, Sally, who has difficulty reading. One of the measures you use to evaluate your interventions is to record the amount of time between finishing reading one word in a sentence and starting to read the next word. This is a measure of:
