Die Besonderheit des Quasi-Experiments besteht darin, dass keine zufällige Zuordnung der am Versuch teilnehmenden Personen stattfindet. Hello Divya! Thanks for the A2A. A field experiment is one that takes place in a natural setting - the experimenter manipulates some aspects of people’s reality and checks for what effect this has on the targeted outcome.

De term quasi-onafhankelijke variabele wordt gebruikt om te wijzen op een variabele die niet door de onderzoeker wordt gemanipuleerd, maar die voor verschillende proefpersonen gewoon anders is. a true experiment blll still want to address causal questions. In these situ ations we can use quasi-experimental designs. Using quasi-experiments in clinical and field situations to draw cautious causal inferences is preferable to not experimenting at all. Quasi-experimental designs resemble experiments but are weak on some of the The word experiment is a broader term because it could include a pre-experiment, (which is not actually an experiment), a quasi-experiment and a true experiment.

Ein Quasi-Experiment ist ein Forschungsdesign und gehört in der Systematik der Versuchspläne zu den vier Haupttypen von Experimenten. Der Begriff Experiment bezeichnet Untersuchungen, die eine Aussage über einen Kausalzusammenhang zweier Variablen ermöglichen. Ein Quasi-Experiment vergleicht natürliche Gruppen ohne randomisierte Zuordnung von Versuchspersonen. Das Untersuchungsdesign determiniert den Wert der kausalen Schlussfolgerungen, die anhand der empirischen Befunde
