Question 11

Topography

Answer 11

Form or shape of the response, not the function

Question 12

Magnitude

Answer 12

Force, intensity, severity of the behavior

Question 13

Continuous Measurement Procedures

Answer 13

Measurement conducted in a manner such that ALL instanced of the response class are detected during the observation period (event recording)

Question 14

Discontinuous Measurement Procedures

Answer 14

Measurement conducted in a manner such that some instances of the response class of interest may not be detected (time sampling methods)

Answer 18

Whole Interval Recording
Partial Interval Recording
Momentary Time Sampling

Question 19

Planned Activity Check

Answer 19

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

Question 20

Ethics Warning: Measurement

Answer 20

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

Question 21

Ethics Warning: Planning Observation

Answer 21

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

Question 22

Scheduling Observation and Recording Periods

Vailidity

Answer 24

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

Accuracy

Answer 27

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

Question 28

Measuring True Values

Answer 28

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

Question 29

Reliability

Answer 29

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