Measurement Basics
Why do we measure behavior in ABA?
To understand behavior and track progress.
What does duration measure?
How long a behavior lasts.
What does latency measure?
Time between instruction and response.
True or False: All behaviors should be measured the same way.
False
Name one common data collection mistake.
Unclear start or end points.
True or False: Behavior measurement should be objective.
True
Is duration better for short behaviors or long behaviors?
Long behaviors
When does latency timing start?
When the instruction is given.
Which measure is best for behaviors that last a long time?
Duration
Why is guessing time a problem?
It can be inaccurate.
What does objective mean when collecting data?
Based on observable facts, not opinions.
Which behavior is best measured with duration: tantrums or eye blinking?
Tantrums
Which behavior fits latency: responding to name or on-task behavior?
Responding to name.
Which measure is best for delayed responses?
Latency
What happens if instructions change during latency measurement?
The data can be misleading.
Who usually collects behavior data during sessions?
RBT
When do you stop timing duration?
When the behavior ends.
Is latency useful if there is no clear instruction?
No.
What can happen if the wrong measurement is used?
Progress can be missed or behavior exaggerated.
Why should timers be reset between trials?
To keep data accurate.
Why is data better than memory when tracking behavior?
Data is more accurate and consistent.
Why is duration better than frequency for tantrums?
It shows how long the tantrum lasts.
Why is latency helpful when a learner already knows a skill?
It shows how quickly they respond.
Why is choosing the right measure important?
It makes the data meaningful.
Why is missing data during a session a problem?
It gives an incomplete picture of behavior.
