Research Strategies Flashcards
What is experimental research?
Experimental research involves manipulating one variable (independent) and measuring its effect on another (dependent), with random assignment to groups.
What is a quasi-experimental design?
Quasi-experimental designs manipulate an independent variable but lack random assignment, which can introduce confounding variables.
What is non-experimental research?
Non-experimental research involves observing and measuring variables without manipulating them. It is often used in correlational studies.
What are single-case research designs?
Single-case research designs focus on the detailed study of a single individual or group, often over time.
What are the advantages of experimental research?
Advantages include the ability to establish cause-and-effect relationships and control for extraneous variables.
What are the limitations of quasi-experimental designs?
Limitations include reduced internal validity due to the lack of random assignment.
When would a researcher use a non-experimental design?
When manipulation of variables is not possible or ethical, such as in observational or correlational studies.
What is a longitudinal research design?
A longitudinal design follows the same participants over time, measuring how they change across various stages of life or development.
What is a cross-sectional design?
A cross-sectional design compares different groups at a single point in time to understand differences based on age or other variables.
