What are the main differences between experimental and non-experimental studies?
What will be an ideal response?
The key difference between experimental and non-experimental research lies in the extent to which the environment is controlled and manipulated by the researcher. In experimental studies the researcher sets up the environment and carefully controls the variables s/he is interested in. Non-experimental research takes place in a real-life setting, and it is not possible for the researcher to control all possible variables. This means that it is harder to determine causality in non-experimental studies, but also that they tend to be more flexible and allow for a greater range of topics to be studied.
