Advantages and disadvantages of quasi experimental design
Answers
Answer:
The lack of random assignment into test groups leads to non-equivalent test groups which can limit the generalizability of the results to a larger population. Beside of the lack of randomization and the reduced internal validity, conclusions about causality are less definitive in quasi-experimental designs.07-Sep-2018
ADVANTAGES
•Quasi experimental designs are more frequently used because they are more practical and feasible to conduct research.
• Where the sample size is small, and where randomization & availability of control group is not possible, this design is preferred.
• Quasi experimental design is more suitable for real natural world setting than true experimental designs.
• This design allows the researchers to evaluate the impact of quasi independent variables under naturally occurring conditions.
• In some cases hypotheses are practically answered through this design.
DISADVANTAGES
• In this design there is no control over extraneous variables influencing the dependent variable.
• The absence of a control group and absence of control over the research setting makes the result of this design less reliable and weak for the establishment of causal relationship between independent & dependent variable.
