Ch.3 Graphing Behavior and Measuring Change Flashcards
Graph
visual representation of the occurrence of a behavior over time
Shows results of recording during many observation periods
What 2 variables does a graph show you
Time and behavior
What are the components of a graph
- x and y-axis
- axis numbers (with hashmarks)
- axis labels
- data points (connected by line)
- Phase lines
- Phase labels
What dimensions can be shown on a graph
frequency
rate
duration
latency
intensity
percentage of intervals of the bx derived from interval recording or time sample recording or the percentage of opportunities in which bx occurred (percentage correct)
Level
How high or low the data are on the y-axis
(If Tx is supposed to decrease bx, level of bx should be lower in Tx phase than in BL phase)
(If Tx is supposed to increase bx, level of bx should be higher in Tx phase than in BL phase)
Trend
Exists when the bx is increasing across a phase or decreasing across a phase
Variability
How high and low the data points are away from the mean level in the phase
(Low = data points are all close to the mean level in a phase)
(High = many data points are far above or below mean)
What is the purpose of research designs
Purpose of a research design is to determine whether Tx (IV) was responsible for the observed change in the target bx (DV) and to rule out the possibility of extraneous variables causing the bx change

How is a functional relationship established
-Target bx changes when an IV is manipulated, while all other variables are held constant
-IV manipulation is replicated or repeated one or more times and the bx changes each time
