Write short note on experimental reserach design?
Experimental research design involves manipulating one or more variables in a controlled setting to observe the effect on the dependent variable. It allows researchers to establish cause-and-effect relationships by controlling for potential confounding variables. This design is characterized by random assignment of participants to different conditions and the use of control groups to minimize bias and increase the internal validity of the study.
What are the advantages and disadvantages of ex post facto research?
advantages:its ideal for testing demographic variables which cannot be manipulated. like a non-experimental design it doesn't require much to collect data, but just merely shows effects of a presence or absence of an Independent variable on a Dependent variable.disadvantages:it cannot acquire as much data as an experimental design, the levels of the "IV" are already established. If anything it tries to be an experimental design but it cannot.

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.
