Which scoring rule describes momentary time sampling when the observer checks at the end of each interval?

A
Score the interval positive if behavior occurred at any time during it.
B
Check whether behavior is occurring at a specified instant, such as the interval's end.
C
Score the interval positive only if behavior continued throughout it.

During a 10-second interval, a behavior occurs only from second 4 through second 7. How is this interval scored using partial-interval recording?

A
Negative, because the behavior did not last for the entire interval.
B
Positive, because the behavior occurred at least once during the interval.
C
Negative, because only behavior occurring at the interval's end counts.

True or false

True or false: In partial-interval recording, several occurrences of the behavior within the same interval still contribute only one positive interval.

An observer scores $2$ of $8$ intervals positive. Using $\frac{\text{positive intervals}}{\text{total scored intervals}}\times100$ , what percentage of intervals are positive? Enter the percentage value.

An observer uses momentary time sampling at the end of each interval. In interval 5, the behavior occurs during the final 2 seconds. How should interval 5 be scored?

A
Negative, because the behavior did not occur throughout the interval.
B
Positive, because the behavior is occurring at the interval's end.
C
Negative, because momentary time sampling counts only behavior that occurs throughout an interval.

C
Duration recording
D
Partial-interval recording

Select all procedures that should be established to support consistent interval data collection.

A
Define the behavior clearly.
B
Specify the interval length.
C
Specify the exact moment for momentary time sampling.
D
Use the same procedure across observations.
E
Change the scoring method between observations without accounting for the change.

A partial-interval recording result is $75\%$ positive intervals. Which interpretation is justified?

A
Behavior occurred at least once in $75\%$ of the scored intervals; this does not establish that it occupied $75\%$ of the observation time.
B
Behavior occupied exactly $75\%$ of the observation time.
C
Behavior occurred continuously during $75\%$ of the scored intervals.

What is a general effect of using shorter intervals, according to the guidance on sampling choices?

A
They always eliminate scoring errors.
B
They generally provide finer temporal detail, although practical suitability also matters.
C
They make interval percentages directly interchangeable across methods.

A teacher's partial-interval percentage rises from one session to the next. Explain why this result alone does not prove the behavior occupied more time, and name two procedural factors that could affect the comparison.

An observer wants to measure sustained engagement and uses a rule requiring engagement throughout each interval. Which method matches that rule?

A
Score the interval positive if the behavior occurs at any point during it.
B
Score the interval positive only if the behavior occurs throughout the entire interval.
C
Score the interval positive if the behavior occurs at the interval's end.
D
Score the interval positive if the behavior occurs more than once.

An observer uses momentary time sampling and checks at the end of each interval. The behavior occurred earlier in an interval but stopped before the end. How should that interval be scored?

A
Score the interval positive because the behavior occurred at some point during it.
B
Score the interval positive only if the behavior occurred throughout the interval.
C
Score the interval negative because the behavior is not occurring at the interval's end.
D
Score the interval positive if the behavior occurred more than once.

During one interval, a behavior occurs three separate times, each briefly. Under partial-interval recording, how many positive intervals should be counted for that interval?

A
Count the interval as one positive interval.
B
Count the interval as several positive intervals, one for each instance.
C
Score the interval positive only if behavior continues throughout it.
D
Score the interval positive only if behavior is occurring at the interval's end.

True or false

1 point

True or false: A momentary time-sampling estimate must be lower than the actual amount of behavior because behavior between observation moments can be missed.

True
B
False

What is the name of the observation approach that divides an observation into equal time periods and scores a defined behavior according to a rule for each period?

Written response

A teacher wants a practical way to observe a frequent behavior with variable duration that is difficult to count continuously. The observation will be divided into equal time periods, and each period will be scored according to a defined rule. What is this broad measurement approach called?
