Unit 2 Flashcards
In Behavior Analysis data is:
Graphed (charted)
standard celeration chart
fit all bx’s in one chart
no change in y-axis
length of observation taken into account
relatively simple visual formats for displaying data
graph
used for summarizing and comparing data for different groups of subjects and/or different conditions
bar graph (histogram)
“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.”
cumulative record
What is this?

Scatter Plot
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
scatter plot
Types of Graphs
- bar graph
- cumulative record
- equal interval line
- semi-logarithmic
(standard celeration)
bar graphs
summarize and compare data for groups/conditions
data points
individual value of the DV
uses of equal-interval line graphs
- track client’s progress
- evaluate effectiveness of interventions
- present results of functional analyses
considerations during visual analysis of data
number of data points
level and mean shift
variability
trend
horizontal axis
passage of time
whole units
“A two-dimensional graph with a logarithmic schaled y axis so that equal distances on the vertical axis represent changes in behavior that are of equal proportions
semi-logarithmic graph
phase change line
major changes in interventions or environemental events

Bar graph (histogram)
equal interval line
- each point represents a relationship between two dimensions,
- most commonly used,
- evaluates treatment effectiveness
vertical axis
represents target behavior/dependent variable
variability
changes within phases
Changes in an intervention should be denoted by a __, while changes in the parameters of an intervention should be denoted by a __.
Phase change line (solid line); Condition change line (dotted line).

Graph type?

Equal-Interval line graph
interpreting graphs
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 manipulation? how certain are we?
“the overal direction taken by the data path”
trend
the value on the vertical axis scale around which a set of behavioral measures converge (mean or median).
level
