Many types of Quasi-experimental designs exist. Here we explain three of the most common types: nonequivalent groups design, regression discontinuity, and natural experiments.

Quasi-Experimental Design and Methods. This guide, written by Howard White and Shagun Sabarwal for UNICEF looks at the use of Quasi-Experimental design and methods in Impact Evaluation. The paper provides a brief overview and then provides an outline of when it is appropriate to use and some of the ethical and practical limitations of its use.

Easy guide to trading the Quasimodo Pattern The Quasimodo Pattern or Over and Under pattern is a relatively new entrant to the field of technical analysis in the financial markets. Although new, the Quasimodo pattern is a commonly occurring theme that is more frequent when price carves a top or a bottom or when price begins a major correction to the trend.

Legal Definition of Quasi (Entry 1 of 2) : having such a resemblance to another thing as to fall within its general category a Quasi corporation
Aa a Quasi-experimental method, ITS contains a strong inferential power and has wide applications in epidemiology, medication research, and program evaluations in general. Arguably, ITS is the strongest Quasi-experimental method in causal inference ( Penfold and Zhang, 2013 ).
Although new, the Quasimodo pattern is a commonly occurring theme that is more frequent when price carves a top or a bottom or when price begins a major correction to the trend. The Quasimodo Pattern, although complex as it might seem is actually very simple.
But the most troubling thing, according to researchers, is simply how opaque and unaccountable these Quasi -medical tools are.
Quasi-experimental design is most useful in situations where it would be unethical or impractical to run a true experiment. Quasi-experiments have lower internal validity than true experiments, but they often have higher external validity as they can use real-world interventions instead of artificial laboratory settings.
One of the intended purposes for doing Quasi-experiment research is to capture longer time periods of different events to control for various threats to validity and reliability. Examples of Quasi-experiment research design are the natural experiment or trend analysis.
The main difference of a Quasi-experiment with a true experiment is the lack of randomised participant selection. It is almost similar to true experiments yet lacks the degree of control over its internal validity. Pre-test and post-test assessments are conducted to provide plausible evidences to support the experiment outcomes.
Though Quasi-experiments are sometimes shunned by those who consider themselves to be experimental purists (leading Donald T. Campbell to coin the term "queasy experiments" for them), they are exceptionally useful in areas where it is not feasible or desirable to conduct an experiment or randomized control trial.
