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 treatment or control.
Ex post facto recruitment methods are not considered true experiments, due to the limits of experimental control or randomized control that the experimenter has over the trait. This is because a control group may necessarily be selected from a discrete separate population. This research design is thus considered a quasi-experimental design.
In statistics, econometrics, political science, epidemiology, and related disciplines, a regression discontinuity design (RDD) is a quasi-experimental pretest–posttest design that aims to determine the causal effects of interventions by assigning a cutoff or threshold above or below which an intervention is assigned.
Interrupted time series analysis (ITS), sometimes known as quasi-experimental time series analysis, is a method of statistical analysis involving tracking a long-term period before and after a point of intervention to assess the intervention's effects.

Quasi-empirical methods aim to be as closely analogous to empirical methods as possible. [ 1 ] Empirical research relies on, and its empirical methods involve experimentation and disclosure of apparatus for reproducibility , by which scientific findings are validated by other scientists.
The Summary. Obesity dipped slightly in U.S. adults last year for the first time in more than a decade, a study found. The researchers suggested that might be due, in part, to the rise of weight ...
