Displaying and Interpreting Behavioral Data Flashcards

Graphs
Visual format for displaying data
3 Purposes of Graphs
CAID Communicate Assess IV DV
5 Benefits of Graphs
Picture on a behavior Explore variations Judgemental aid Conservative method for determining significance Independent judgement
5 Types of ABA Graphs
LBCSS Line Bar Cumulative Records Semilogarithmic Charts- Standard Celeration Chart Scatter Plot
Equal Interval Graphs
Graphs in which distance between any 2 consecutive points on X and Y are always the same
Intervals are the same size
Line Graphs
Most common graphs in ABA
Based on Cartesian Plane
Y axis shorter than x
Comparing data points examines level, trend, and variability
AKA for Equal Interval graphs
Arithmetic Charts
Add-Subtract Charts
AKA for Line Graph
Frequency Polygons
7 Parts of a Line Graph
Horizontal Axis Vertical Axis Condition Change Lines Condition Labels Data Points Data Path Figure Caption
Horizontal Axis
X, Abscissa
Passage of time
Left to right
Vertical Axis
Y, Ordinate
Full range of values of DV
Condition Change Lines
Vertical line drawn upward from X to show points in time at which changes in IV occurred
Solid-Major
Dashed- Minor
Condition Labels
Written at top of parallel to the x describing experimental condition
Data Points
A measure of target behavior recorded during observation
Time and or experimental condition under which that particular measurement was conducted
Data Path
Connects successive data points with a straight line
Illustrates level and trend of behavior between points
Figure Caption
Concise statement provides information to identify the IV and DV
Bar Graphs
Based on Cartesian Plane
No distinct data points representing successive response measures through time
No variability or trend
Displaying separate sets of data not relating to each other
Summarizing performance within condition
Cumulative Records
Developed by Skinner to record data in EAB
Keep adding on responses during each observation period to the total number of all previously recorded
Only increases until data path resets
Cumulative Record Response Rates
Steeper slope higher response Rate/frequency 2 types of response rates Overall Response Rate Local Response Rate
Overall Response Rate
An average rate of response over a given time period such as during a specific session or phase
Local Response Rate
During periods of time smaller than that for which an overall response rate has been given
Semilogarithmic Charts
Logarithmic scales look at behavior change through proportional or relative change
All behavior changes of equal proportion are shown by equal vertical distances on the vertical axis
Standard Celeration Chart
A type of Semilogarithmic Chart
Ogden Lindsley created it to be used in an ABA educational methodology called Precision Teaching
Academic and social behaviors are charted
Students self monitor their progress by recording data
Goal-To increase the number of correct answers and decrease the number wrong within the set time
Scatter Plots
Shows relative distribution of individual measures in a data set
Data points unconnected
To be used when you want data to effectively communicate temporal distribution of behavior and may help to identify elusive environmental stimuli
3 Fundamental Properties of Behavior Change
LTV
Level
Trend
Variability
Level
Value on vertical axis around with a series of data measures converge
Levels are examined by looking at mean, median and or range
Mean- Average
Median-Middle
Trend
Overall direction taken by the data path
Described in terms of direction, degree, extent of variability
Trend line drawn through data to show trend
