BCABA EXAM
1. measure frequency
*Answer√√ count, tally of occurrences. behavior being measured this way should be discrete with clear
beginning and end.
2. rate
*Answer√√ number of responses per unit of time.
3. duration/ temporal extent
*Answer√√ entire length of time behavior occurs.
4. latency
*Answer√√ A measure of temporal locus; the elapsed time from the onset of a stimulus to the initiation of a
response. ex. how long it takes the individual to respond once the SDis presented
5. IRT inter-response time
*Answer√√ time between two responses
6. percent of occurrence
*Answer√√ number of times the target behavior occurred/ the number of trials or oppor-tunities
7. trials to criterion

, BCABA EXAM
*Answer√√ how long does it take to achieve mastery? mastery is a predetermined level of perfor-mance.
8. IOA interobserver agreement
*Answer√√ the degree to which two or more independent observers report the same observed values
after measuring the same events
9. total count IOA
*Answer√√ A percentage of agreement between the total number of responses recorded by two
observers and is calculated by dividing the smaller of the two counts by the larger and multiplying by 100.
Smaller/larger x 100. Tends to overestimate IOA.
10. mean count per interval
*Answer√√ find the percent for each interval by dividing the small count by the larger
count. Add all the percentages up and the divide by the total number of intervals, %IOA 1 + %IOA 2 + %IOA 3 +%IOA
(etc.) divided by Total#of intervals X 100
11. exact count per interval IOA
*Answer√√ number of intervals of 100% agreement divided by the total number
of intervals. this is multiplied by 100%, Most stringent for most data sets obtained by event recording

12. trial by trial IOA*Answer√√ # of Trials in agreement divided by total number of trials X 100
13. total duration IOA*Answer√√ A relevant index of IOA for total duration measurement; computed by
dividing the shorter of the two durations reported by the observers by the longer duration and multiplying by
100.
14. Mean duration per occurrence IOA*Answer√√ An IOA index for duration per occurrence data;
also a more conservative and usually more meaningful assessment of IOA for total duration data calculated for a
given session or measurement period by computing the average percentage of agreement of the durations reported
by two observers for each occurrence of the target behavior.
15. interval-by-interval IOA*Answer√√ the agreement between two observers per each interval;
calculated by
dividing total number of intervals agreed by the total number of intervals and multiplying by 100
16. scored interval IOA*Answer√√ only intervals with occurrence agreements used for low rate bx..do
not count nonoccurrence bx!!!!!!
