Non-experimental research focuses on attempting to study the correlation/relationship between two things. It studies the variables, but unlike experimental, it differs in that these variables are not being manipulated. An example I think of for non-experimental is patients with ICU delirium. Not all patients admitted to the ICU will develop delirium because ICU alone does not cause derlium, but there is a strong chance/relationship if certain measures aren’t taken. This can ultimately lead to worse patient outcomes.
