RBT #1 Measurement

When we refer to the validity of a measurement system, we are referring to what?

Data are directly related to the behavior being measured and the reasons for measuring it

Samantha collected the total number of times Edward slapped the table over three separate 1 hour observation periods. Afterwards, she calculated the total number of times Edward slapped the table per hour.

Rate

What is one of the advantages of rate data collection?

Allows us to directly compare behavior when the observation period might vary in length

Sarah collected the duration of time it took her father to finish doing the dishes after dinner, measuring from the onset of washing (putting soap on the first dish) till the offset of washing (drying and putting away the last dish). Sarah should have helped her father do the dishes, by the way. What type of data collection does this describe?

Duration

The onset to start recording the length of time a behavior takes - specifically, crying (with or without tears) for longer than 10 seconds. The offset is described as the total absence of crying (with or without tears) for at least 10 seconds. What type of data collection does this most likely describe?

Duration

Samantha collected the total number of times Edward slapped the table and said "Well how about that!" during Thanksgiving dinner.

Frequency

DISCONTINUOUS data collection records a sample of behavior, not an exact record of each instance of behavior.

Partial Interval, Whole interval, Momentary Time Sampling

What does onset refer to?

The beginning of an event, in the

What does reliability of a measurement system refer to?

The extent to which a measurement system yields the same value upon repeated tests
