Term

Definition
A simple and versatile graphic format for summarizing behavioral data; shares most of the line graph's features except that it does not have distinct data points representing successive response measures through time. Also called a histogram.



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 the responce in real time; each time a responce is emitted, a pen moves upward accross paper that continuously moves at a constant speed. 


Term

Definition
The results of measurement, usually in quantifiable form; in applied behavior analysis, it refers to measures of some quantifiable dimension of a behavior.



Term

Definition
The level and trend of behavior between successive data points; created by drawing a straight line from the center of each data point in a given data set to the center of the next data point in the same set.



Term

Definition
The variable in an experiment measured to determine if it changes as a result of manipulations of the independent variable; in applied behavior analysis, it represents some measure of a socially significant behavior.



Term

Definition
A visual format for displaying data; reveals relations among and between a series of measurements and relevant variables.



Term

Definition
The variable that is systematically manipulated by the researcher in an experiment to see whether changes in the independent variable produce reliable changes in the dependent variable. In applied behavior analysis, it is usually an environmental event or condition antecedent or consequent to the dependent variable. Sometimes called the intervention or treatment variable.



Term

Definition
The value on the vertical axis around which a series of behavioral measures converge.



Term

Definition
Based on a Cartesian plane, a twodimensional area formed by the intersection of two perpendicular lines. 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
The average rate of response during a smaller period of time within a larger period for which an overall response rate has been given.



Term

Definition
The rate of response over a given time period.



Term

Definition
A twodimensional graph that shows the relative distribution of individual measures in a data set with respect to the variables depicted by the x and y axes. Data points on a scatterplot are not connected. 


Term

Definition
A twodimensional graph with a logarithmic scaled y axis so that equal distances on the vertical axis represent changes in behavior that are of equal proportion. 


Term
SplitMiddle Line of Progress 

Definition
A line drawn through a series of graphed data points that shows the overall trend in the data; drawn through the intersections of the vertical and horizontal middles of each half of the charted data and then adjusted up and down so that half of all the data points fall on or above and half fall on or below the line. 


Term
Standard Celeration Chart 

Definition
A multiplydivide chart with six base10 (or x 10, /10) cycles on the vertical axis that can accommodate response rates as low as 1 per 24 hours (0.000695 per minute) to as high as 1,000 per minute. It enables the standardized charting of celeration, a factor by which rate of behavior multiples or divides per unit of time.



Term

Definition
The overall direction taken by a data path. It is described in terms of direction (increasing, decreasing, or zero trend), degree (gradual or steep), and the extent of variability of data points around the trend. Trend is used in predicting future measures of the behavior under unchanging conditions.



Term

Definition
The frequency and extent to which multiple measures of behavior yield different outcomes.



Term

Definition
A systematic approach for interpreting the results of behavioral research and treatment programs that entails visual inspection of graphed data for variability, level, and trend within and between experimental conditions.
