Concept information

Preferred term

quasi experiments  

Definition(s)

  • Quasi experiments, like all experiments, manipulate treatments to discover causal effects (quasi experiments are sometimes referred to as nonrandomized experiments or observational studies). However, these experiments differ from randomized experiments in that units are not randomly assigned to conditions. [Source: Encyclopedia of Epidemiology; Quasi Experiments]
