Q

True values

A

A measure acceptable as the quantitative descrescription of the “true state” of an event as it exists

“special or extraordinary precautions to ensure all possible sources of error have been avoided or removed”

Q

Total count IOA

A

Expressed as a percentage agreement between the total number of responses recorded by two observers and is calculated by dividing the smaller of the counts by the larger and multiplying by 100

Q

IOA obtained by event recording

A

Calculated by
A) total count recorded by each observer per measurement period
B) the counts tallied by each observer during each of a series of smaller intervals of time within the measurement period
C) each observers count of 1 or 0 on a trial by trial basis

16
Q

3 techniques for calculating IOA

A

Interval-by-interval
Scored-interval
Unscored-interval

17
Q

Interval-by-interval

A

Likely to overestimate agreements for low and high frequency behaviors

18
Q

Scored interval IOA

A

Recommended for behaviors that occur at a relatively low frequency

19
Q

Unscored interval IOA

A

Recommended for behaviors that occur at high frequencies

20
Q

Line Graph horizontal axis

A

Represents passages of time and presence, absence and value of data

21
Q

Line graph vertical axis

A

Y axis or ordinate: represents a range of values ofnthebdependent values

22
Q

Origin

A

Intersection of vertical and horizontal axis

23
Q

Bar graph

A

Or histogram. In ABA used for comparing discrete sets of data that are not related to one another

24
Q

Cumulative Records

A

Developed by Skinner. Primary means of data collection in the experimental analysis of behavior. Cumulative recorder used to record the data

25
Q

Precision teaching

A

Developed for use with standard celebration chart.

Focuses on celebration not frequency of incorrect vs. correct responses

26
Q

Precision teaching is predicated on the position that:

A

A) learning is best measured as change in response rate
B) learning most often occurs through proportional changes
C) past changes in performance can project future learning
