Question

Quasi-experimental designs are used particularly in circumstances where it is not possible to implement classical experimental designs. In this design, researchers have no control over the independent variable. Using your own understanding, explain how the types of quasi-experimental designs differ in terms of their characteristics 

Answer 1

Like a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria.
