 | Term | Definition |
| |
data |
the results of measurement, usually in quantifiable form |
| |
graph |
a visual format for displaying data; reveals relations among and between a series of measurements and relevant variables |
| |
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) |
| |
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 |
| |
cumulative recorder |
a device that automatically draws cumulative records that show the rate of response in real time |
| |
data path |
the level and trend of behavior between successive data points |
| |
dependent variable |
the variable in an experiment measured to determine if it changes as a result of manipulations of the independent variable |
| |
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 |
| |
level |
the value on the vertical axis around which a series of behavioral measures converge |
| |
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 |
| |
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 |
| |
overall response rate |
the rate of response over a given time period |
| |
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) |
| |
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 |
| |
split-middle line of progress |
a line drawn through a series of graphed data points that shows the overall trend in the data |
| |
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 |
| |
trend |
the overall direction taken by a data path |
| |
variability |
the frequency and extent to which multiple measures of behavior yield different outcomes |
| |
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 |
| |
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 |
