SCED Foundations
Types of SCED Designs
Validity (Internal & External)
Data Analysis
100
Data taken to determine effects of the IV.
What is baseline data?
100
It is the simplest, yet least robust method.
What is AB design?
100
The extent to which an experiment shows convincingly that changes in the dependent variable is a direct result of the applied model (intervention).
What is internal validity?
100
It allows for more precise analysis of change.
What is visual analysis?
200
The participants serve as their own.
What is control?
200
It is the most solid method for demonstrating experimental control.
What is withdrawal, reversal, ABAB, etc. design?
200
Extraneous variables that occur for the participant that could influence the study.
What is history effects?
200
Demonstrates the meaningfulness of that data to the individual/group.
What is social validity?
300
This is a key element to understanding the data.
What is variability?
300
It negates ethical concerns of withdrawing treatment but may be timely to implement.
What is multiple baseline design?
300
It is instrumental to internal validity and involves two+ observers taking data simultaneously to determine reliability.
What is interobserver agreement?
300
There should be less than ______ overlap of data points between phases.
What is 25%
400
Rather than comparing to a mean of a large amount of participants, it looks at individual differences to determine treatment effect.
What is how it differs from group design?
400
It utilizes step-wise increases or decreases in criterion to demonstrate experimental control.
What is changing-criterion design?
400
An individual's natural tendency to change over time.
What is maturation?
400
There is an immediate change in _______ which demonstrates experimental control.
What is level?
500
It is defined objectively, descriptively, and is based on observable behavior.
What is operational definition?
500
It consists of random selection of intervention type to demonstrate experimental control.
What is alternating treatments design?
500
Across behavior, across settings, and across time...
What is generality in external validity?
500
Experimental control of intervention 1 alone is demonstrated by a change in ______.
What is variability?
