This is always the case for ex-post impact evaluation designs. It may also be necessary to use quasi-experimental designs for ex-ante Quasi-experimental research involves the manipulation of an independent variable without the random assignment of participants to conditions or orders of conditions. Among the important types are nonequivalent groups designs, pretest-posttest, and interrupted time-series designs. A quasi-experiment is a research method used in the design of an experiment of an empirical study used to estimate the causal impact of an intervention on its target population. Quasi-Experimental Design Quasi-Experimental Design is a unique research methodology because it is characterized by what is lacks. For example, Abraham & MacDonald (2011) state: "Quasi-experimental research is similar to experimental research in that there is manipulation of an independent variable. A quasi-experimental design is one that looks a bit like an experimental design but lacks the key ingredient – random assignment.

Quasi-experimental Research Designs. True Quasi-experimental Research Designs – in which a treatment or stimulus is administered to only one of two groups

what is the quasi-experimental method? ‘Quasi’ means resembling or ‘having some, but not all of the features of’. So, quasi-experimental designs are almost identical to true experimental designs, but lacking one key ingredient namely, random assignment .

So, quasi-experimental designs are almost identical to true experimental designs, but lacking one key ingredient namely, random assignment.

In these situations, quasi-experimental designs may provide a solution, as these allow for causal conclusions at the 19 Feb 2020 Objective: To assess the efficacy of music therapy in reducing anxiety in patients undergoing interventional technique (IT) in the Pain Unit (UD) of the University Hospital Sagrat Cor in Barcelona. Material and method: Qua 10 Oct 2019 According to), a quasi-experiment is a research design with no random distribution of participants, but in which other conditions for the conduction of an experiment are met (use of pre and post-test and control group).

3. Include intervention or treatments but lack degree of “control”. e.g. Lack of Randomization. 4. Quasi-experimental approaches are similar in that they compare units that are part of a development intervention with those that are not.
