Question 1

Partial interval recording tends to do which of the following to the reported occurrence of behavior?

Accepted Answer

Overestimate it

Answer

Partial interval recording scores an interval as an occurrence if the behavior appears at any point, even briefly, causing overestimation of how much behavior actually occurs.

Question 2

In whole interval recording, behavior is scored as occurring only if:

Accepted Answer

It persists throughout the entire interval

Answer

Whole interval recording requires that the behavior be present for the full duration of the interval; if it stops even briefly, the interval is scored as a non-occurrence.

Question 3

Momentary time sampling (MTS) records behavior:

Accepted Answer

Only at the precise moment each interval ends

Answer

In MTS the observer checks at the exact instant the interval ends and records only whether the behavior is occurring at that snapshot moment.

Question 4

Which IOA method is most appropriate for low-frequency behaviors to avoid inflated agreement scores?

Accepted Answer

Occurrence IOA

Answer

Occurrence IOA calculates agreement only in intervals where at least one observer recorded the behavior, preventing the inflation caused by the many shared 'no behavior' intervals.

Question 5

Point-by-point interobserver agreement compares observer data at the level of:

Accepted Answer

Each individual interval or trial

Answer

Point-by-point IOA evaluates agreement for every interval separately, then averages those scores, making it a sensitive measure of moment-to-moment consistency.
