Quasi-experimental designs lack several elements of true experimental designs, including the researcher's control over the timing of the experiment, the selection of subjects, and the ability to randomize assignment to treatment and control groups. These limitations are due to the nature of quasi-experiments, which are often used in situations where true experimental designs are not feasible.
