Unit 3 T

Question 1

Continuous response measures directly measure_______ of behavior while discontinue his response measures involve_______

Answer 1

Dimensional quantities: dimensionless quantities

Discontinuous or in direct response measures do you not directly measure dimensional quantities, most involved occurrence versus non-occurrence and are often expressed in percent.

Question 2

Ray is a student in a class with 26 other students, one teacher, and two teachers aides. Which of the following response measures would be the best for his teacher to use to collect data on raising hand behavior, which his teacher estimates occurs less than seven times per month, 1 to 2 times a week or so?

Answer 2

Event recording

Even with a limited teacher to student ratio, event recording is most accurate and workable because this is a low rate behavior that is easy to discriminate.

Question 3

Partial interval recording, whole interval recording, and momentary time sampling all typically….

Answer 3

Are reported as a percentage.

Because all three of these methods break observations into intervals the typical manner for representing these data is percent of recorded intervals during which the behavior occurred.

Question 4

Bobby’s aggression are brief but intense. If aggression occurs at 5 o’clock, 530, 7 o’clock, and 8 o’clock, what is the average IRT?

Answer 4

60 minutes

The time between occurrences is 30 minutes, 90 minutes, and 60 minutes. Adding those numbers equals 180 minutes and dividing by three, the number of IRT measurements, yield an estimated average I RT of 60 minutes

Question 5

Estimate the IRT if the rate of aggression is 12 times per hour

Answer 5

Five minutes.

The formula for estimating the IRT is the formula for rate inverted. The formula for rate is frequency overtime. The formula for estimated average IRT is time over frequency, unit of time divided by the number of responses. In general this calculation should be used only for behavior with responses that are relatively evenly disbursed over an observation period. In other words, estimated average IRT does not work well with responses that tent a cluster together in a long observation.

Question 6

Select the discontinuous in direct response measure that would be most appropriate for use to measure a moderate rate behavior, targeted for reduction

Answer 6

Partial interval recording.

Is used for reductive targets only. It indicates whether the behavior occurred at any time during an interval so tends to over estimate the occurrence of behavior, although for a very high rate target behaviors it can’t underestimate the occurrence

Question 7

For most behavior partial interval recording tends to—— it’s occurrence; for very high rate behavior, partial travel recording tends to _____its occurrence

Answer 7

Overestimate, underestimate

Question 8

All of the following dimensional quantities are based on a combination of two fundamental properties, repeatability and temporal locus, except:

Answer 8

Duration.

Rate, celeration , I RT are dimensional quantities based on the combination of repeatability and temporal Lucas

Question 9

Which of the following is the best example of data

Answer 9

Time spent pacing the Corridors
