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 o...

Study the different types of quasi-experimental design through use of real-life study examples. Compare quasi-experimental design with true...
In either case, quasi-experimental designs allow you to study the question by taking advantage of data that has previously been paid for or collected by others (often the government). Advantages and disadvantages Quasi-experimental designs have various pros and cons compared to other types of stud...
Example: Quasi-experimental design You study whether gender identity affects neural responses to infant cries. Your independent variable is a subject variable, namely the gender identity of the participants. You have three groups: men, women and other. ...
However, in case of quasi-experimental studies, the treatment effects may not be strictly comparable. For instance, studies that use a regression discontinuity design or instrumental variable method typically estimate local average treatment effect (LATE), while those using propensity score matching ...
Ex post facto design is considered a quasi-experimental type of study, which means that participants are not randomly assigned, but rather grouped together based upon specific characteristics or traits they share. Ex post facto research focuses on how actions that have already occurred can predict ...
Similar to quasi-experimental methods, this type of research focuses on relationship differences between variables. This approach provides a fast and easy way to make initial hypotheses based on either positive or negative correlation trends that can be observed within dataset. Methods used for data ...
This dissertation presents a quasi-experimental study design to evaluate non-random\\\-ized, pre-existing community interventions not originally designed to gather rigorous data about sustainability and impact. The core components of the design include selection of a control group using propensity score...
Types of Quasi-Experimental Designs One type of quasi-experiment is thenonequivalent group design. This means that the existing groups are not divided or randomly assigned. The experimental and control groups are usually not equal in the number of participants. This design is useful for the...
