Chapter 6- Constructing and Interpreting Graphic Displays of Behavioral Data Flashcards
Data
The medium with which behavior analysts work, product of measurement.
Graphs
Relatively simple formats for visually displaying relationships among and between a series of measurements and relevant variables.
Line graph
Most common graphic format in ABA. Two dimensional, shows relationship between the dependent and independent variable. Includes: horizontal axis, vertical axis, axis labels, condition change lines, condition labels, data points, data path, figure caption
Data path
Connecting data points on a line graph.
Bar graph
A simple and adaptable format for graphically summarizing data. Bar graphs sacrifice the variability and trends in data.
Cumulative recorder
A device that automatically draws a graph of a subject’s rate of behavior.
Cumulative record
Constructed by adding the number of responses recorded during each observation period to the total number of responses recorded during all previous observation periods.
Overall response rate
The average rate of response over a given time period.
Local response rate
The rate of responses during periods smaller than that for which an overall rate has been given.
Ratio scale
Well suited for displaying proportional change. Equal vertical distances correspond to equal ratios of change in the variable being measured.
Standard celeration chart
A standardized means of charting and analyzing how frequency of behavior changes over time.
Precision teaching
Developed for use with the standard celeration chart. Based on that learning is best measured as a change in response rate, learning occurs through proportional changes in behavior, and past changes in performance can project future learning.
Scatterplots
Graphic display that shows the relative distribution of individual measures in a data set with respect to the variables depicted by the x and y axes. No data path.
Visual analysis
An examination to interpret graphically displayed data.
Variability
How often and the extent to which repeated measures of behavior yield different outcomes.
