Q

Calibration

A

If errors are found as you evaluate the measurement system, you will correct and improve by making the necessary adjustments to make sure the measurement system is accurate.

Q

Direct Measurement

A

The observer is present and taking data, in real time, when the behavior is occurring.

Firsthand.

Q

IOA

A

Inter-observer agreement: 2 or more observers are collecting data on a behavior and confirming whether their observations are congruent with one another.

Q

Mean Duration Per Occurrence IOA

A

Duration IOA Bx1 + duration IOA Bx 2 + etc / # of duratino IOAs x 100

Temporal/Duration IOA
Use for duration per occurrence data.

Most precise temporal IOA.

Q

Measurement Bias

A

When the data is assumed to have a certain outcome, so the observer tries to make sure their data reflects the predetermined outcome or goal.

Q

Naive Observer

A

The observer, who was formally trained on the intervention, still does not fully understand why they are observing and recording data on the client’s behavior.

Q

Observed Value

A

A measure produced by an observation and measurement system. Serves as the data that the researcher and others will interpret to form conclusions about an investigation.

16
Q

Observer Drift

A

Without knowing, the observer changes the way they are implementing the system measuring the behavior.

17
Q

Observer Reactivity

A

When the observer acts differently because they know they are being observed and results in measurement artifacts (errors in their recording and data).

18
Q

Reliability

A

Can you repeat the measurement and get the same result?

19
Q

Scored Interval IOA

A

Number of intervals both recorded occurrence / number of intervals 1 person recorded occurrence x 100

Use for bxs that occur at frequencies of 30% of intervals or fewer.

Time Sampling IOA

20
Q

Total Count IOA

A

Smaller # / Larger # x 100

Repeatability measuring IOA.
Simplest repeatability measure IOA.

Overestimates the extent of actual agreement.

21
Q

Total Duration IOA

A

Shorter duration / Longer duration x 100

Overestimates extent of actual agreement.

22
Q

Trial by Trial IOA

A

Number of trials in 100% agreement / total number of trials x 100

Use for DIT.

23
Q

True Value

A

Is what I’m measuring accurate?

24
Q

Unscored Interval IOA

A

Number of intervals both recorded non-occurrence / number of intervals 1 recorded non-occurrence x 100

Use for behaviors that occur at frequencies of 70% of intervals or more.

25
Q

Validity

A

Are you measuring the right thing?

26
Q

3 Types of IOA

A
  1. Event recording/repeatability.
  2. Temporal/timing/duration.
  3. Time sampling/interval recording procedures.
27
