Experimental Group Designs
What is the relationship between treatment effect size and sample size?
As treatment is more robust (larger effect), fewer participants are required to detect change
If treatment effects are smaller, a larger sample is needed to detect the effects
What type of design can be used to strengthen the experimental control in a single-subject design?
Multiple baseline design
What kind of survey question is “In your opinion, what are the three most important issues facing the field of communication sciences and disorders?”?
What is an Open-Ended Question?
The type of reasoning that qualitative research relies on.
What is inductive reasoning?
What are the four stages of action research?
What is Planning, acting, developing, and reflecting?
What is the difference between true experimental vs quasi group designs?
True experimental designs utilize random assignment when determining their control/experiment groups, quasi group designs do not.
Ideally over how many sessions would one collect an adequate number of baseline measures to ensure quality?
Five or more
What are the four problems associated with survey error?
What are Sampling error, measurement error, coverage error, and non-response error?
The goal of qualitative research.
What is interpretive adequacy?
What does the reflection stage contain?
What is sharing and communicating the results of the study?
What is a factorial research design?
Researchers plan to manipulate two or more independent variables simultaneously. Researchers can determine how more than one independent variable impacts a dependent variable plus they can determine how the two independent variables work together
What notation would be used to symbolize a treatment replication design?
A1 – B1 – A2 - B2
What is the main difference between experimental and nonexperimental research design?
What is experimental research designs manipulate their variables, nonexperimental research designs do not
T/F - Qualitative researchers usually set up an experiment to control specific factors.
What is false?
What steps does the planning stage include?
Identifying and limiting the topic, gathering information, reviewing the related literature, and developing a search plan.
What is the difference between random assignment and random selection?
Random selection is to identify a sample of individuals who will participate in the study from a larger population
Random assignment is to divide all the participants into different treatment groups
Single subject designs fit into the category of what type of experimental design?
Quasi-experimental design
A threat to this type of nonexperimental design’s internal validity is subject mortality.
What are longitudinal studies?
This type of research is often used in the field of anthropology and encompasses several methods of studying events or behaviors within a cultural context.
What is an ethnography?
The goal of action research.
What is to diagnose problems and develop effective and efficient solutions?
R O X O O
R O O X O
This is an example of what type of experimental design?
Switching Replications Design
What are the five types of single case design?
ABA, ABAB, (Baseline, Treatment, Withdrawal)
ABAB or ABC - Alternating Treatments
Multiple Baseline
Changing Criterion
Simultaneous Treatments
A cohort study is classified under what kind of non-experimental research?
Longitudinal research
The three steps of inductive reasoning (in order).
What is gather data in written statements, identify trends, formulate a theory?
What is “acting” in action research?
What is implementing the plan and collecting data
What is analyzing the data
