24 participants leave the experiment...
Attrition
a factor other than the treatment variable that might have an effect on the outcome variables
Extraneous Variable
TRUE OR FALSE: Another name for this is a "True Experiment"
TRUE
TRUE OR FALSE: All single case experiments share two elements: a baseline condition and a control condition.
False: Treatment
study where researchers manipulate one variable to determine its effect on another variable
Experiment
developmental changes affect the outcome variables in an experiment
Maturation Effect
TRUE OR FALSE: Natural Observations are NOT an example of a measure that can be used for this experiment
FALSE (includes tests, questionnaires, and interviews)
TRUE OR FALSE: In an A-B-A design, a treatment condition is typically designated as “B.”
TRUE
each participant has an equal chance of being in either group
Random Assignment
changes in the measuring instrument affect the results of an experiment
Instrumentation Effect
TRUE OR FALSE: The POST TEST VARIABLES are the causes, and the EXPERIMENTAL/CONDITION VARIABLES are the effects.
FALSE, it is the opposite
Using reinforcement or modeling techniques to increase/decrease the frequency of specified behaviors
Behavior Modification
an experiment with experimental and control groups but without random assignment of participants to these groups
Quasi Experiment
show an improvement on the posttest simply as a result of their experience with the pretest is an example of
Testing Effect
TRUE OR FALSE: It's either an experimental group or no intervention at all. The control group CANNOT receive a "scaled-down version of a program".
FALSE
TRUW OR FALSE: Single-case experiments TYPICALLY test the effectiveness of interventions that will be delivered to any population of people.
FALSE: Persons with special needs that have a low population incidence (e.g., autism)
an experiment having more than one factor
Factorial Experiment
The experimental intervention is NOT implemented accordingly to the specifications of the researchers or program developers
Treatment Fidelity
statistical significance of group differences can be determined by
EITHER 1 or all 3: analysis of variance, analysis of covariance, or multiple regression
In a single case experiment, the researcher might _____ the research design with several similar individuals to determine whether the intervention effects recur.
