Ex-post facto research measures the cause and effect relationship without manipulating the independent variable. While the experimental research starts from manipulating and controlling the independent variables and proceeds to observing the effect on the dependent variables.

It is easy in experimental research to interpret the effect of independent variable on dependent variable while it isn’t so in ex post facto research due to effect of extraneous variables

What is a Quasi Research Design in Research methodology?

A quasi-experimental research design is a type of research methodology that lacks full experimental control but still allows for comparison between groups. It involves manipulating an independent variable to observe its impact on a dependent variable, but lacks random assignment to groups. This design is often used when true experimentation is not feasible or ethical.

What kind of research design is most commonly used by researchers?

The most commonly used research design is the experimental design, where researchers manipulate one or more variables to observe their effect on an outcome. This design allows for causal relationships to be established between variables.

What is a quasi experimental design?

A quasi-experimental design is a research method that resembles an experimental design but lacks the element of random assignment to groups. This means that the groups are not formed randomly, making it less able to establish causation between variables. It is often used when true experimentation is not feasible due to ethical, logistical, or practical reasons.


What is the difference between research design and methodology?

Research design refers to the overall plan that outlines how a research study will be conducted, including the approach, procedures, and data collection methods. Methodology, on the other hand, refers to the theoretical framework or process used to conduct research, outlining the specific techniques and tools that will be used to gather and analyze data. In summary, research design is the blueprint of the study, while methodology is the strategy for executing that blueprint.

Is quasi-experimental design a qualitative study?

Quasi experiments aren't really experiments they are better known as difference studies. Experimental research is using different experiments to find an answer or solution.
