Q

A mean count per interval calculation of interobserver agreement is percent agreement for each interval…

A. Divided by the number of observers

B. Added across all intervals

C. Averaged across all intervals

D. Averaged across observers

A

C

A frequency-within-interval calculation increases the probability that agreements are based on both recorders observing the same behaviors. The calculation is percent agreement for each interval averaged across all intervals. For example, in the first interval, observer one records two occurrences and observer two Records for occurrences (50%). In the second interval, observer one records one occurrence and observer two record three occurrences (33%). The sum of 50%, 33%, etc., would be divided by the total number of intervals.

Q

Interobserver agreement may be influenced by…

A. The number of individuals upon whom data are being collected

B. The complexity of the disorder

C. The social impact of a person’s disability

D. All of the above

18
Q

Which reflects the logic behind the need to report occurrence/non-occurrence agreement data. “Their interval by interval agreement is high, but…

A. Their occurrence/non-occurrence agreement is high as well”

B. their overall agreement is even higher“

C. Because the behavior is so frequent, they appear to be recording occurrences when there were none“

D. Because the behavior occurs so rarely, I think they may be comparing data sheets or prompting each other when the behavior occurs“

A

C

19
Q

An acceptable criterion for inter observer agreement data…

A. Can be lower than 80% when there is a large degree of variability across conditions

B. Can be lower than 80% when there is a small degree of behavior change across conditions

C. Should be higher than 80% when there is a large degree of behavior change across conditions

D. Should be higher than 80% when there is a small degree of behavior change across conditions

A

D

20
Q

Computation of data…

A. Should be the exclusive responsibility of data collectors

B. Is not needed in single subject research

C. By data collectors should be supplemented with computation by others

D. By data collectors is advised due to their familiarity with the data

A

C

21
Q

Which reflects the logic behind the need to report nonoccurrance agreement data. “interval by interval agreement is high, but…

A. We know that already. I want to know when it is low“

B. Overall agreement is high too. This is unlikely if the data are accurate“

C. Because the behavior is so rare, I think observers just don’t care“

D. Because the behavior is so frequent, I think observers just score each interval“

A

D

22
Q

To calculate inter-observer agreement on frequency measures….

A. Divide the frequency of one observer by the sum of the frequency of both observers

B. Divide the number recorded by the observer who recorded the fewest by the number recorded by the other observer who recorded the most

C. Divide the number of intervals in which both observers recorded an occurrence by the total number of intervals in which both observers recorded a non-occurrence

D. Divide the number recorded by the observer who recorded the most by the number recorded by the other observer who recorded the fewest

A

Q

To calculate non-occurrence interobserver agreement, divide the…

C. Number of intervals in which both observers recorded an occurrence by the number of intervals in which at least one observer recorded an occurrence

D. Number of intervals in which both observers recorded an occurrence by the total number of intervals
