Answer 1

do not capture all instances of behavior during an observation period

Question 2

Interval recording:

Type:

Answer 2

discontinuous measurement

Question 3

Interval recording:

Observation period is:

Answer 3

divided into smaller time periods with established occurrence and non-occurrence criteria established

Question 4

Partial-interval recording (PIR)

Answer 4

occurrence is noted if behavior occurs ANY TIME during the interval

Question 5

PIR stands for

Answer 5

Partial-Interval Recording

Question 6

Whole-interval recording (WIF)

Answer 6

Occurrence is noted if behavior occurs for the entire interval

Question 7

WIR stands for

Answer 7

Whole-Interval Recording

Question 8

Momentary-Time Sampling (MTS)

Answer 8

occurrence/nonoccurrence is observed and recorded at the end of the interval

MTS stands for

Answer 9

Momentary-Time Sampling

Question 10

Planned Activity Check (PLACHECK)

Answer 10

Number of group members engaging in the behavior is noted at the end of the interval
