100

Which of the two (frequency or rate) provides more accurate data?

Rate

100

What does duration measure?

How long a behavior lasts.

100

What does latency measure?

Time between instruction and response.

100

What is being measured when taking IRT data?

Time between two responses
100

Why is guessing time an issue when taking measurement data?

Data becomes inaccurate

200

What is the formula for finding the rate of a behavior?

Frequency รท Time

200

What types of behaviors are appropriate for duration?

Behaviors with a clear beginning and end

200

What type of behaviors are appropriate for latency measurement?

Behaviors that should have a faster or slower response rate

200

The client engaged in SIB at 3:05 then again at 3:30. What is the IRT?

15 minutes
200

Which system is best used for measuring delayed responses?

Latency
300

The client engages in 9 instances of biting within a 3-hour session? What is the rate of the behavior?

3 instances of biting per hour

300

When taking duration data, when should you stop recording?

At the offset or end of the behavior

300

When taking latency data, you should begin data collection?

After the instruction or SD has been delivered

300

While taking IRT data, two RBTs debate when to start the timer. When should timing begin?

At the END of the first behavior
