C08 Evaluate the Validity and Reliability Part 2 Flashcards
Which is the correct interval by interval calculation of IOA?
90%
A mean count per interval calculation of IOA is percent agreement for each interval
Averaged across all intervals
Which is the correct nonoccurrence calculation of IOA?
60%
To calculate IOA on frequency measures,
Divide the number recorded by the observer who recorded the fewest by the number recorded by the other observer who recorded the most x100
Which is the correct interval by interval calculation of IOA?
80%
Observer A pushups= 7; Observe B pushups = 9; What is the IOA?
78%
To calculate occurrence IOA, divide the
Number of intervals in which both observers recorded an occurrence by the number of intervals in which at least one observer recorded an occurrence x100
Observer A = 6, Observe B =9. What is the IOA?
67%
To calculate IOA on duration measures, divide the
Time recorded by the observer who recorded the shortest duration by the time recorded by the observer who recorded the longest duration x100
Which is the correct occurrence calculation of IOA?
71%
Which reflects the logic behind the need to report nonoccurrence agreement data. “Interval by interval agreement is high, but
Because the behavior is so frequent, I think observers just score each interval
Airport baggage…. which question reflects the logic behind the need to report occurrence/nonoccurrence agreement data?
Can they detect when contraband is present and not present?
To calculate interval by interval IOA, divide the
Number of intervals in which both observers agreed by the total number of intervals x100
To calculate nonoccurrence IOA, divide the
Number of intervals in which both observers recorded no occurrence by the number of intervals in which at least one observer recorded no occurrence x100
