Q

3 Forms of Time Sampling (WPM)

A

Whole Interval Recording
Partial Interval Recording
Momentary Time Sampling

19
Q

Planned Activity Check

A

A group version of momentary time sampling where the teacher count the number of students engaging in the behavior at the end of the interval

20
Q

Ethics Warning: Measurement

A

Select a measurement method that provides the most ethical and valid description of the target behavior

21
Q

Ethics Warning: Planning Observation

A

Truly capture what the target behavior really looks like when you conduct data collection

22
Q

Scheduling Observation and Recording Periods

A

Think about the time of day, week, weather conditions, task assignments, etc.

23
Q

3 Indicators of Trustworthy Measurement (VAR)

A

Validity
Accuracy
Reliability

24
Q

Vailidity

A

Directly measuring socially significant behaviors and ensuring that the data are representative of the behavior occurrence under conditions during relevant times.

25
Q

Threats to Measurement Validity

A

Indirect Measurements, Measuring the wrong dimension of the target behavior, Measurement artifacts

26
Q

Measurement Artifcacts

A

Discontinuous measurement
Poorly scheduled measurement periods
Insensitive/limited measurement scales

27
Q

Accuracy

A

The extent to which the observed value matched the true value of an event

28
Q

Measuring True Values

A

Process must be different than the measurement procedure for the observed values.

29
Q

Reliability

A

the extent to which a measurement procedure uyiled the same value when brought into repeated contact with the same state of nature.

30
Q

Threats to Measurement Reliability

A

Human error
Poorly designed measurement
Inadequate observer training
Expectations about what the data should look like

31
Q

Observer Drift

A

hen an observer unknowingly alters the way they measure a behavior

32
Q

Measurement Bias

A

Nonrandom measurement error that is likely to be in one direction.

33
Q

Observer Reactivity

A

Measurement error resulting from an observer’s knowledge that others are evaluating the data that she reports

34
Q

Interobserver Agreement

A

The degree to which 2 or more independent observers report the same values after measuring the same events

35
Q

3 Requisites for Obtaining IOA

A

Observing must use the same measurement System
Same Event
Observers must be independent

36
Q

4 Event Recording IOA’s (TMET)

A

Total Count IOA
Mean Count-per-Interval IOA
Exact Count-per-Interval IOA
Trial by Trial IOA

37
Q

2 Timing/Duration IOA’s (TM)

A

Total Duration IOA

Mean Duration-per-Occurrence IOA

38
Q

3 Interval Recording/Time Sampling IOAs (ISU)

A

Interval-by-Interval IOA
Scored Interval IOA
Unscored Interval IOA

39
Q

Total Count IOA

A

Smaller number divided by larger number multiplied by 100%

40
Q

Mean Count-per-Interval IOA

A

INT1 IOA + INT2 IOA etc. divided by the total number of intervals.

41
Q

Exact Count-per-Interval IOA

A

Number of Intervals of 100% IOA divided by Total number of intervals times 100%

42
Q

Trial by Trial IOA

A

of trials of agreement divided by total number of trials times 100%

43
Q

Total Duration IOA

A

Shorter Duration / Longer Duration x 100%

44
Q

Mean Duration-per-Occurrence IOA

A

IOAB1 + IOAB2 etc / # of Behaviors with duration IOA that occurred
