The key difference between experimental and observational study is that an experimental study is a study where the researcher has control over most of the variables. On the other hand, an observation study is a study where the researcher merely observes the subject without controlling any variables.

Otherwise, it is probably a c ontrolled study. In an observational study, values of the explanatory variable occur naturally. In this case, this means that the participants themselves choose a method of trying to quit smoking. In an experiment, researchers assign the values of the explanatory variable. In other words, they tell people what method to use.
Both designs need to have randomization or else their results are garbage. In observational studies the condition of randomization is met by randomly selecting the sample. Experiments do not typically have that luxury because oftentimes it is not ethical.

Designed Experimental Study - Unlike an observational study, an experimental study has the researcher purposely attempting to influence the results. The goal is to determine what effect a particular treatment has on the outcome.

2009-04-26 · In an observational study, the scientist goes and observes things as they happen, with no interference. They just look, record data and think about what that means. Manipulative experiments involve going out, specifically changing factors being studied, and seeing how things change. Experiments have control groups, where that factor is not changed.
