1
Q

Validity

A

Does the data actually measure what it’s supposed to measure?

Best done though direct measurement during times of most concern

Text book example: you would not measure soreness to determine the a amount of miles a bicyclist has ridden

2
Q

Accuracy

A

Does the measurement reflect the true value of the behavior?

Example:

3
Q

Reliability

A

Are measurements consistent?

Example: a scale that consistently says 3lbs lighter even though this is not accurate

4
Q

Conservative Sample

A

Used when assessing intervention

Times when the frequency of the behavior is most likely to be different (higher or lower) than the desired treatment outcome

5
Q

Calibration

A

Comparing data obtained to its true value

Process for establishing true values must be different than the procedures from the other measurement procedure

6
Q

Interobserver Agreement: Definition

A

Extent to which two independent observers agree on the occurrence and nonoccurrence of a target behavior

Data on this should be taken at least 33% of sessions

7
Q

Event Recording: Total Count

A

Smaller Total/Larger Total x 100 = % Agreement

**Simplest
Total count of responses per measurement period

8
Q

Event Recording: Mean Count per Interval

A

Divide total observation period into equal times and have observers record responses for each time period. Then divide by the total number of intervals and multiply by 100

9
Q

Event Recording: Exact Count per Interval

A

Percent of intervals in which the two observers recorded the same frequency of behavior

**most stringent

10
Q

Event Recording: Trial by Trial

A

agreements/ agreements + disagreements x 100

For response opportunity data (either occurrence (1) or nonoccurrence (0))

11
Q

Duration/Latency Data: Total Duration

A

Smaller Time/ Larger Time x 100

No assurance that the same durations are being recorded for the same occurrence of the behavior

12
Q

Duration/Latency: Mean Duration per Occurrence

A

Take: smaller/larger x 100 for each occurrence. Then, average this across all occurrences

13
Q

Interval: Interval by Interval or Total Interval

A

intervals Agreement / Total Intervals x 100

**how many intervals where they agreed on the occurrence and nonoccurrence of the behavior

14
Q

Interval: Scored Interval

A

Only comparing intervals where both observers note the occurrence of the behavior.

Good for low rate behaviors since it ignores chances where scoring a nonoccurrence is very likely

15
Q

Interval: Unscored Interval

A

Considering intervals where either one or both observers recorded a nonoccurrence

Good for behaviors that occur at high rates
