EXPERIMENTAL Vs NON EXPERIMENTAL STUDY DESIGNS

 

INTRODUCTION:  In studying causality, when a researcher or someone else introduces the intervention that is assumed to be the ‘cause’ of change and waits until it has produced – or has been given sufficient time to produce – the change, then in studies like this a researcher starts with the cause and waits to observe its effects. Such types of studies are called experimental studies.

NON-EXPERIMENTAL STUDIES

There are times when, in studying causality, a researcher observes an outcome and wishes to investigate its causation. From the outcomes the researcher starts linking causes with them. Such studies are called non-experimental studies. In a non-experimental study you neither introduce nor control/manipulate the cause variable. You start with the effects and try to link them with the causes.
