Continuous Measurement
What measurement tells you how many times a behavior happens?
What is frequency?
In discontinuous measurement, do you record every single occurrence of the behavior?
No
How many times did it happen?
frequency
A child hits their sibling 7 times. You count every hit. What are you using?
Frequency
Which is better for a behavior that happens very frequently: continuous or discontinuous measurement?
Discontinuous measurement.
A tantrum lasts 12 minutes. What type of measurement should you use?
duration recording
The behavior only needs to happen at some point during the interval. What type is this?
partial-interval recording?
"How long did it last?"
duration
A child cries for 15 minutes. What are you measuring?
Duration
Which measurement asks, "Is the behavior happening right now?"
Momentary time sampling.
A teacher says, "Start your work." The student starts 45 seconds later. What are you measuring?
latency
The behavior must occur for the entire interval. What type is this?
whole-interval recording?
How long did it take to start?
latency
Every 5 minutes, you look at a student and record whether they are on-task at that exact moment. What are you using?
Momentary time sampling.
Which measurement asks, "Did the behavior happen at any time during the interval?"
Partial-interval recording.
A student calls out, and 3 minutes later calls out again. What measurement tells you the time between these responses?
IRT (Interresponse Time)
You check the student at the exact moment the interval ends. What type is this?
momentary time sampling
How much time passed between two responses?
IRT
You observe a student for 20 minutes divided into 1-minute intervals. If the student is off-task at any point during the minute, you mark "yes." What are you using?
Partial-interval recording.
Which measurement asks, "Did the behavior happen for the whole interval?"
Whole-interval recording.
You want to know how many times a student leaves their seat during a 30-minute class. Which measurement would you use?
frequency/
A student is constantly moving around during class. Counting every movement is difficult. What type of measurement might be useful?
discontinuous measurement?
What is the main difference between continuous and discontinuous measurement?
You record the behavior every time it happens.
Discontinuous: You record behavior during specific intervals or moments.
ou observe a student for 20 minutes divided into 1-minute intervals. The student must remain on-task for the entire minute for you to mark "yes." What are you using?
Whole-interval recording.
A student has tantrums. You want to know both how many tantrums occur and how long each tantrum lasts. Which two measurements would you use?
Frequency + Duration.
