While the advantages of observational research might appear attractive, you need to weigh them against the cons. However, it is possible to study the exposed population living in affected areas using observational studies. For example, it might not be ethical to expose people to harmful variables, such as radiation. Sometimes the observational method is the only way to study some things, such as exposure to specific threats. ![]() Doing observational research can also be pretty simple because you do not have to keep looking into multiple variables, and trying to control some groups.In that case, all you need is to ask any interested students to participate in a survey with questions, such as “yes” and “no.” Suppose you take the example of a study looking at the impact of introducing a new learning method into a school. Because the observational study does not require the use of control, it is inexpensive to undertake.If you are thinking of carrying a research and have been wondering whether to go for randomized experiment vs observational study, here are some key advantages of the latter. Again, unlike the observational study statistics, which are considered biased and weak, evidence from experimental research is stronger. The main difference between an observational study and an experiment is that the latter is randomized. For example, the study did not factor in the possibility of viewers watching other films. Therefore, even if the study point to some relationship between the main variables, it is considered too weak. The researcher in the study does not have any control over the participants. We will demonstrate this with an example.Ī study asking people how they liked a new film that was released a few months ago is a good example of an observational study. When an observational report is released, it indicates that there might be a relationship between several variables, but this cannot be relied on. It is simply a matter of observing what is happening. Therefore, the researcher observes the impact of a specific risk factor, such as treatment or intervention, without focusing on who is not exposed. ![]() So, what is an observational study? This is a form of research where the measurement is done on the selected sample without running a control experiment. ![]() ![]() To understand observational study vs experiment, let us start by looking at each of them. Keep reading to understand the difference between observational study and experiment. For example, does eating fast food result in teenagers being overweight? Or does going to college increase the chances of getting a job? Most studies fall into two main categories, observational and experimental studies, but what is the difference? Other widely accepted research types are cohort studies, randomized controls, and case-control studies, but these three are part of either experimental or observational study. The primary goal of doing a study is to evaluate the relationship between several variables. For you to know the quality of the research findings, it is paramount to start by understanding some basics of research/study design. When we read about research studies and reports, many are times that we fail to pay attention to the design of the study.
