Here’s a table that summarizes the similarities and differences between experimental and quasi-experimental study designs: A quasi-experimental study is a non-randomized study used to evaluate the effect of an intervention. The intervention can be a training program, a policy change or a medical treatment. Vid kvasiexperiment (quasi-experimental design) utsätts experimentgruppen för en särskild påverkan (experimentvariabel) som kontrollgruppen inte utsätts för. Man undersöker effekten av experimentvariabeln genom att jämföra utfallen i experiment- och kontrollgruppen.
