Term
|
Definition
| A simple and versatile graph format for summarizing behavior data; shares most of the line graph’s features except that it does not have distinct data points representing successive response measurements 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 |
|
|
Term
|
Definition
A device that automatically draws cumulative records (graphs) that show the rate of response in real time; each time a response is emitted, a pen moves upward across paper that continuously moves at a constant speed.
The result of measurements, usually in quantifiable form; in applied behavior analysis, it refers to measures of some quantifiable dimension of 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 ABA it represents some measure of socially significant behavior |
|
|
Term
|
Definition
| A visual format for displaying data; it 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 ABA, it is usually an environmental event or condition antecedent or consequence to the dependent variable. Sometimes called the intervention or treatment variable |
|
|
Term
|
Definition
| The value on the axis around which a series of behavioral measures converge |
|
|
Term
|
Definition
| Based on a Cartesian, a two dimensional 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 ABA |
|
|
Term
|
Definition
| The average rate of response during a smaller period of time within a larger period of time for which an overall response rate has been given. |
|
|
Term
|
Definition
| The rate of response over a given time period |
|
|
Term
|
Definition
| A two-dimensional graph that shows the relative distribution of individual measures in a data set with respects to the variables depicted by the x and y axes. Data points on a scatterplot are not connecte. d |
|
|
Term
|
Definition
| A two-dimensional graph with a logarithmic scaled y axis so that distances on the vertical axis represents change in behavior that are of equal proportion |
|
|
Term
| Split Middle 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 or down so that half of all data points fall on or above and half fall on or below the line. |
|
|
Term
| Standard Celeration Chart |
|
Definition
| A multiply-divide chart with six base-10 (or x10, divided 10) cycles on the vertical axis that can accommodate response rates as low as 1 per 24 hours (0.000695 per minute) as high as 1,000 per minute. It enables the standardized charting of celeration, a factor by which rate of behaviors multiplies or divides |
|
|
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 |
|
|
Term
|
Definition
| A systematic approach for interpreting the results of behavior research and treatment programs that entails visual inspection of graphed data for variability, level, and trend within and between experimental conditions |
