Term
| Visual analysis (criterion by inspection) |
|
Definition
“The evaluation of an experimental or clinical
manipulation via visual inspection of graphed data.” |
|
|
Term
|
Definition
|
• Displayed in a table (in summary form).
• Graphed (charted) |
|
|
Term
|
Definition
| “Relatively simple visual formats for displaying data.” |
|
|
Term
| Types of graphic displays |
|
Definition
|
• Cumulative record
• Equal-interval line graph
• Semi-logarithmic graph |
|
|
Term
|
Definition
- Used for summarizing and comparing data
for different groups of subjects and/or
different conditions.
• Used to compare sets of data which are not
related to one another by a common
underlying dimension by which the
horizontal axis can be scaled. That is, the
data are discrete. |
|
|
Term
|
Definition
“A type of graph on which the cumulative number
of responses emitted is represented on the vertical
axis; the steeper the slope of the data path, the
greater the response rate.” |
|
|
Term
|
Definition
“A device that automatically draws cumulative
records (graphs) that show the rate of response in
real time; each time a response is emitted, a pen
moves upward across paper that continuously
moves at a constant speed.” |
|
|
Term
| Equal-interval line graph |
|
Definition
A type of graph “based on a Cartesian plane… Any
point within the plane represents a specific relation
between the two dimensions described by the
intersecting lines. It is the most common graphic
format for displaying data in Applied Behavior
Analysis.” |
|
|
Term
|
Definition
“A two-dimensional graph with a logarithmic
scaled y axis so that equal distances on the
vertical axis represent changes in behavior that
are of equal proportions. |
|
|
Term
| Uses of equal-interval line graphs |
|
Definition
|
• Evaluate effectiveness of interventions
• Present results of functional analyses |
|
|
Term
|
Definition
- Did a significant change in one of the
dimensions of the target behavior occur
between one phase/condition and the next?
• Was the change due to the manipulation?
How certain are we? |

|
Term
| Considerations during visual analysis of data |
|
Definition
|
• Level and mean shift (in level)
• Variability
• Trend |
|
|
Term
|
Definition
The value on the vertical axis scale around which a
set of behavioral measures converge (mean or
median). |
|
|
Term
|
Definition
| “The overall direction taken by the data path.” |
|
|
Term
|
Definition
“The extent to which measures of behavior under
the same environmental conditions diverge from one
another.” |
|
|
Term
|
Definition
A data collection form for problem behavior and the
intervals of time behaviors occurred. It provides a
graphic display of data in a grid format. It is used to
identify patterns of responding in natural settings. |
