An experimental design is one in which participants are randomly assigned to levels of the independent variable. As we saw in our (“Quasi-Experimental”) Study. Designs Are Most Likely to.

Quasi-experimental designs resemble experiments but are weak on some of the characteristics. Quasi-experiments include a comparison of at least two Quasi-experimental research designs, like experimental designs, test causal hypotheses. A quasi-experimental design by definition lacks random assignment. Quasi-experimental designs identify a comparison group that is as similar as possible to the treatment group in terms of baseline (pre-intervention) characteristics.

Revised on March 8, 2021. 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.

Both experimental and quasi-experimental studies aim to prove a causal relationship between an intervention/treatment and an outcome. However they differ in their designs. In an experiment (a.k.a. randomized controlled trial ), we take participants and divide them at random to be in one of 2 groups:

Simply de ned, the independent . True experimental research randomises participants for their control group and treatment group however, with quasi-experimental research, participants are selected for groups by criteria beyond the researcher’s control (Kowalczk, 2015). Lesson 1: Characteristics of Quantitative Research https://youtu.be/zDC819pehWg Lesson 2: Strengths and Weaknesses of Quantitative Research (Part 1) https:// The difference is that in a quasi-experiment the criterion for assignment is selected by the researcher, while in a natural experiment the assignment occurs 'naturally,' without the researcher's intervention. Quasi-experiments have outcome measures, treatments, and experimental units, but do not use random assignment.

Quasi-experimental research designs do not randomly assign participants to treatment or control groups for comparison.

Even so, the question remains as to how useful experimental and quasi- experimental designs are in public health. Here is one view relating to health education

Explain what quasi-experimental research is and distinguish it clearly from both experimental and correlational research. Describe three Quasi-experimental research designs, like experimental designs, test causal hypotheses. The main difference is that the former lacks random assignment to a Experimental Study (a.k.a. Randomized Controlled Trial), Quasi-Experimental Study.
