Quasi-Experimental Design
Revised on January 22, 2024. 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. Instead, subjects are assigned to groups based on non-random criteria.
Quasi-Experimental Research Design
Quasi-experimental design is a research method that seeks to evaluate the causal relationships between variables, but without the full control over the independent variable (s) that is available in a true experimental design. In a quasi-experimental design, the researcher uses an existing group of participants that is not randomly assigned to ...

Quasi-Experimental Research Designs by Bruce A. Thyer. This pocket guide describes the logic, design, and conduct of the range of quasi-experimental designs, encompassing pre-experiments, quasi-experiments making use of a control or comparison group, and time-series designs. An introductory chapter describes the valuable role these types of ...
Quasi-experimental Research: What It Is, Types & Examples
Quasi-experimental research is a quantitative research method. It involves numerical data collection and statistical analysis. Quasi-experimental research compares groups with different circumstances or treatments to find cause-and-effect links. It draws statistical conclusions from quantitative data.
Quasi Experimental Design Overview & Examples
Quasi-experimental research is a design that closely resembles experimental research but is different. The term "quasi" means "resembling," so you can think of it as a cousin to actual experiments. In these studies, researchers can manipulate an independent variable — that is, they change one factor to see what effect it has.
Quasi-Experimental Research
The prefix quasi means "resembling." Thus quasi-experimental research is research that resembles experimental research but is not true experimental research. Although the independent variable is manipulated, participants are not randomly assigned to conditions or orders of conditions (Cook & Campbell, 1979). [1] Because the independent variable is manipulated before the dependent variable ...
How to Use and Interpret Quasi-Experimental Design
A quasi-experimental study (also known as a non-randomized pre-post intervention) is a research design in which the independent variable is manipulated, but participants are not randomly assigned to conditions. Commonly used in medical informatics (a field that uses digital information to ensure better patient care), researchers generally use ...
Quasi-Experimental Design: Types, Examples, Pros, and Cons
See why leading organizations rely on MasterClass for learning & development. A quasi-experimental design can be a great option when ethical or practical concerns make true experiments impossible, but the research methodology does have its drawbacks. Learn all the ins and outs of a quasi-experimental design.
Quasi-experiment
A quasi-experiment is an empirical interventional study used to estimate the causal impact of an intervention on target population without random assignment. Quasi-experimental research shares similarities with the traditional experimental design or randomized controlled trial, but it specifically lacks the element of random assignment to ...
Quasi-Experimental Research
Quasi-Experimental Research. The prefix quasi means "resembling.". Thus quasi-experimental research is research that resembles experimental research but is not true experimental research. Recall with a true between-groups experiment, random assignment to conditions is used to ensure the groups are equivalent and with a true within-subjects ...
The Use and Interpretation of Quasi-Experimental Studies in Medical
In medical informatics, the quasi-experimental, sometimes called the pre-post intervention, design often is used to evaluate the benefits of specific interventions. The increasing capacity of health care institutions to collect routine clinical data has led to the growing use of quasi-experimental study designs in the field of medical ...

Citation. Reichardt, C. S. (2019). Quasi-experimentation: A guide to design and analysis. The Guilford Press. Abstract. This volume explains the logic of both the design of quasi-experiments and the analysis of the data they produce to provide estimates of treatment effects that are as credible as can be obtained given the demanding constraints of research practice.
Experimental Research Design
Experimental research design is centrally concerned with constructing research that is high in causal (internal) validity. Randomized experimental designs provide the highest levels of causal validity. Quasi-experimental designs have a number of potential threats to their causal validity. Yet, new quasi-experimental designs adopted from fields ...
An Introduction to Quasi-Experimental Design
Quasi-experimental design has some advantages and disadvantages you'll need to consider when designing your research. On the plus side, quasi-experimental design: Has a higher external validity than true experimental design, as it usually involves real-world scenarios. Allows you to control for unexpected, confounding variables, resulting in ...
Use of Quasi-Experimental Research Designs in Education Research
In the past few decades, we have seen a rapid proliferation in the use of quasi-experimental research designs in education research. This trend, stemming in part from the "credibility revolution" in the social sciences, particularly economics, is notable along with the increasing use of randomized controlled trials in the strive toward rigorous causal inference.
Selecting and Improving Quasi-Experimental Designs in Effectiveness and
QEDs test causal hypotheses but, in lieu of fully randomized assignment of the intervention, seek to define a comparison group or time period that reflects the counter-factual (i.e., outcomes if the intervention had not been implemented) ().QEDs seek to identify a comparison group or time period that is as similar as possible to the treatment group or time period in terms of baseline (pre ...
Experimental vs Quasi-Experimental Design: Which to Choose?
A quasi-experimental design is a non-randomized study design used to evaluate the effect of an intervention. The intervention can be a training program, a policy change or a medical treatment. Unlike a true experiment, in a quasi-experimental study the choice of who gets the intervention and who doesn't is not randomized.
Quasi-experimental design
Quasi-experiments are similar to randomized controlled trials in many respects, but there are many challenges in designing and conducting a quasi-experiment when internal validity threats are introduced from the absence of randomization. ...

What is quasi-experimental research: Types & examples
According to the Cambridge Dictionary, the word quasi is "used to show that something is almost, but not completely, the thing described."And as the name suggests, quasi-experiments are almost experiments because of the way they are conducted.What actually differentiates this type of experiment from true experimental research is the way the subjects are divided.
Experimental and Quasi-Experimental Research
Basic Concepts of Experimental and Quasi-Experimental Research. Discovering causal relationships is the key to experimental research. In abstract terms, this means the relationship between a certain action, X, which alone creates the effect Y. ... In the MegaGro experiment discussed below, the plants might be matched according to ...
Use of Quasi-Experimental Research Designs in Education Research
The increasing use of quasi-experimental research designs (QEDs) in education, brought into focus following the "credibility revolution" (Angrist & Pischke, 2010) in economics, which sought to use data to empirically test theoretical assertions, has indeed improved causal claims in education (Loeb et al., 2017).However, more recently, scholars, practitioners, and policymakers have ...
