What is the difference between an observational study and an experiment
Blizzard [7]

Answer: In observational study observer has no control on the variables but in an experiment experimenter has control over the independent variable to record the change on the dependent variable.

On the other hand an experiment is a process which is done by experimenter to  demonstrate a known fact or create a discovery by applying some methods to the variables  .
