The crucial difference between a quasi-experimental design and a true experimental design is the ability to control variables. In a true experimental design, researchers have control over all variables except for the independent variable, which allows for the establishment of cause-and-effect relationships between variables. Quasi-experimental designs lack this level of control and therefore cannot establish causation with the same degree of confidence as true experimental designs. The level of sophistication and costs can vary between both types of designs and are not defining differences.
