Measurement dimensions (e.g., rate, duration, percentage)
i) Rate: add up the behaviors or items over time
ii) Ex: Mary hits 4 them in two hours which equals to 2 times per hour
iii) Duration: amount of times a behavior occurs
Example: Mary cried from 10am to 10:16am. Thus, Mary cried for a total of 16 minutes. iv)
Percentage: ratio form by combining the same dimensional quantities such as count
(1) Example: Mary got 4 out of 10 which equals to 40%.
independent variable
The variable that is systematically manipulated by the researcher in an experiment to see whether
changes in the independent variable produce reliable changes in the dependent variable. In ABA, it is
usually an environmental event or condition antecedent or consequent to the dependent variable -
Example: Token Economy, Candy, Schedule, Praise, etc
dependent variable
- The variable in an experiment measured to determine if it changes as a result of manipulations of
the independent variable. In ABA, it represents some measure of socially significant behavior -
Example: Behavior - Protesting, Non-compliance, Saying Hi, Mathching Colors, etc.

Measurement procedures (e.g., event recording, timing, time sampling)
i) Event recording: number of times a behavior occurring
(1) Example: Mary gets out of her seat five times without permission during math seat work
ii) Timing: used to measure duration, response latency, inter-response time
iii) Response latency: the amount of time that elapsed after a direction is given before the child
respond. Or in other words, the elapsed time from the onset of a stimulus to the time that the
response started,
(1) Example: The teacher said touch dog, and 4 seconds later, the client touched the dog. The latency
is 4 seconds in this scenario
iv) Inter-response time (IRT): Elapsed time between two successive responses.
(1) Example: 13 seconds passed in between the two instances of screaming.
Skill acquisition data
Any data collected during the intervention that reflects the child current skills or mastered skills
Problem behavior data
i) Behavior data collected during the course of the intervention
