Any experiment that does not utilize true experimental procedures (including random assignment of participants) is considered to be quasi-experimental. True vs. Quasi-Experimental Design There are a few key differences between true experimental design and quasi-experimental design. The table below outline...
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...
Later this aspect of assignment arrangements, randomization, was used to distinguish "true experiments" from "quasi-experiments" (D.T. Campbell & Stanley, 1963). Indeed, the special relationship of randomization to internal validity was given such prominence that the term experiment was taken to ...

High temperature tensile experiment was carried out on a CMT5105 microcomputer control electronic universal testing machine. The high-temperature tensile temperatures were 473 K, 527 K, 573 K, and 623 K, and the initial strain rates were 1.67 × 10−4 s−1,5 × 10−4 s−1,1.67 ×...

Model design The DID method has been widely used in recent years to evaluate the effect of policy implementation as a quasi-experiment exogenous to the economic system (Beck et al. 2010; Bertrand and Mullainathan 2003; Zhang et al. 2020a, b). On the one hand, the implementation of ...
Energy sufficiency Household App Quasi-experiment Energy transition 1. Introduction In Global North countries, households are responsible for the majority of total energy consumption and CO2 emissions (Ivanova et al., 2020): their consumption patterns are an important target for climate mitigation and ...
Through the quasi-natural experiment of ICP policy construction, the BE optimization effect of innovation policy-driven urban transformation and development is systematically evaluated for the first time. Second, compared with previous studies that examined BE from the perspectives of transaction costs and...
HS conceived the study. TK performed the experiment and collected the data. HS and TK analysed the data. HS wrote the manuscript with critical contributions by TK. Both authors read and approved the final manuscript. Corresponding author
