- scatterplot
- a two-dimensional 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 are not connected)
- data path
- the level and trend of behavior between successive data points
- overall response rate
- the rate of response over a given time period
- data
- the results of measurement, usually in quantifiable form
- data path
- 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
- cumulative record
- 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
- independent variable
- 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
- variability
- the frequency and extent to which multiple measures of behavior yield different outcomes
- semilogarithmic chart
- a two-dimensional graph with a logarithmic scaled y axis so that equal distances on the vertical axis represent changes in behavior that are of equal proportion
- cumulative recorder
- a device that automatically draws cumulative records that show the rate of response in real time
- Standard Celeration Chart
- a multiply-divide chart with six base-10 cycles on the vertical axis taht can accommodate response rates as low as 1 per 24 hours to as high as 1,000 per minute
- graph
- a visual format for displaying data; reveals relations among and between a series of measurements and relevant variables
- level
- the value on the vertical axis around which a series of behavioral measures converge
- split-middle line of progress
- a line drawn through a series of graphed data points that shows the overall trend in the data
- line graph
- the most common graphic format for displaying data in applied behavior analysis; any point within the plane represents a specific relation between the two dimensions described by the intersecting lines
- visual analysis
- 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
- dependent variable
- the variable in an experiment measured to determine if it changes as a result of manipulations of the independent variable
- bar graph
- a graphic format that shares most of the line graph's features except that it does not have distinct data points representing succesive response measures through time (also called a histogram)
- trend
- the overall direction taken by a data path
- local response rate
- the average rate of response during a smaller period of time within a larger period for which an overall response rate has been given
