Quizplus · Accepted Answer

When the researcher is unable to achieve full manipulation of scheduling or allocation of treatments, a quasi-experimental design can be used. Quasi-experimental designs allow for some of the apparatus of true experimentation, such as controls and pre- and post-test measurements, but do not have full control over the allocation of treatments. True experimental designs (B) require full control over the allocation of treatments. Statistical designs (C) may refer to the use of a particular statistical test or analysis, rather than the overall design of the study. Preexperimental designs (D) are less rigorous designs that do not include controls or have limited control over the allocation of treatments.
