1

A systematic form of data examination,
characterized by visual inspection of
graphical displays of those data

Visual Data Analysis

2

1. Data may be embedded in text.
2. Data may be presented in summary
form, usually as a structured data
table (a numerical representation of
data).
3. Data may be presented in graphical
form (a visual representation of data).

Types of Data Display

3

A relatively simple visual format for
displaying data.

Graph

4

Equal interval line graph
Cumulative records
Bar graph
Semi logarithmic graphs

Graphic displays used in ABA

5

Based on a Cartesian* plane, a twodimensional
area formed by the intersection
of two perpendicular lines (one vertical, one
horizontal).

Equal Interval Line Graph

6

Any point within the plane of the chart
represents a specific relationship between
the two variables (dimensions) measured
along each of the axis lines.

Simple Line Graph

7

Most commonly used format for
charting ABA data
Used to evaluate treatment
effectiveness
Used in functional analyses

Common uses of Line Graphs

8

The horizontal X-axis
The vertical Y-axis
Data points
The data path
Condition and phase change lines
Condition and phase change labels
Figure legend

Parts of an Equal Interval Line Graph

9

X-axis.
The abscissa.
Represents the passage of time.

Horizontal Axis

10

Y-axis
The ordinate
Represents the range of values of the
dependent variable

Vertical Axis

11

Can be marked according to the needs of the
behavior analyst, to promote the most useful
analysis
Can be marked as any specified
recorded observation periods, over a
period of time

X-Axis Units

12

Equal movements up the Y-axis represent
equal increases in the behavior
The behavior should be expressed in whole
time units

Y-Axis Units

13

Runs from zero up to some number which is
chosen by the creator of the graph

Y-Axis Range

14

An individually measured value of the target
behavior (the DV) at a given point in time

Data Points

15

A series of straight lines connecting
successive data points within a phase or
condition.
It represents the relationship between the IV
and the DV.

Data Path

16

Major changes occur in the independent
variable
A major (usually permanent) change in the
environment

Phase Changes

17

Document phase changes
placed at a point along the X-axis indicating
the point in time when the phase change
occurred
for a clear visual separation between the
data charted before the phase change, and
the data collected after the phase change

Phase Change Lines

18

Minor changes occur in the independent
variable
A minor (usually temporary) change in the
environment

Condition Change Lines

19

States what time periods are represented by
each successive data point

X-Axis Label

20

States what response measure was used to
measure the dependent variable – the target
behavior

Y-Axis Label

21

Brief labels, placed at the top of the chart,
and identify each separate major phase of
treatment

Phase Labels

22

Mark changes occurring within a phase

Condition Labels

23

A concise statement that provides you with:
Sufficient information to identify the
dependent variables and the independent
variables, and
Possibly other salient information necessary
to visually interpret the data.

Figure Legend

24

Level
Variability
Trend
The number of data points

Visual Analysis of Graph

25

The mean (average) value of a set of data
points, usually across an entire condition or
phase.

Level

26

The overall direction taken by the data path
through a set of data points

Trend

27

The extent to which measures of behavior
under the same environmental conditions
diverge from one another.

Variability

28

Outlying data points skew the level line in a
way that makes it non-representative of the
data set as a whole

Median Level

29

The direction and degree of trend in a series
of graphically displayed data points can be
visually represented with a straight line
drawn through the data.

Trend Lines

30

Bisect the data, with close to an equal
number of data points above the line as
below the line.
