|
Quasi experiments do not have controlled variables.
|
|
|
Quasi experiments take place in naturalistic environments; true experiments take place in laboratories
|
|
|
In a quasi experiment, participants have a trait that determines which condition they are in; in a true experiment, they are randomly allocated.
|
|
|
Quasi experiments are cross-sectional; true experiments are longitudinal (take place over a long period of time).

Detailed explanation-1: -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.
Detailed explanation-2: -Some authors distinguish between a natural experiment and a “quasi-experiment". The difference is that in a quasi-experiment, the criterion for assignment is selected by the researcher; while in a natural experiment, the assignment occurs ‘naturally, ‘ without the researcher’s intervention.
Detailed explanation-3: -The primary difference between quasi-experimental research and true experimental research is that quasi-experimental research does not involve random assignment to control and experimental groups.
