Once the research problem has been formed, the researcher organizes a study that will allow him to find answers to the research problem. Observational studies can also be conducted in the natural sciences as well in order to comprehend behavioral patterns. On the contrary, some variables can be beyond the control of the researcher. Worked example identifying experiment. When conducting research studies, the researcher can adopt various types of research in order to arrive at conclusions. Whenever you read about a study or research, see if it is observational or experimental. Because assignment to the independent variables of observational data is usually nonran- dom, the challenge of estimating causal effects with observational data can be formidable.

Of course, the study is not a lie – it’s just data. Very much in a nutshell: only data for which you have all covariates under control, and have either randomization over possible confounders or enough information on them to properly account for them, can be truly called experimental.
