In an experiment, the researcher manipulates a variable.
In Vivo
In an experiment investigators apply treatments to experimental units (people, animals, plots of land, etc.) and then proceed to observe the effect of the treatments on the experimental units. n an observational study investigators observe subjects and measure variables of interest without assigning treatments to the subjects. The treatment that each subject receives is determined beyond the control of the investigator. For example, suppose we want to study the effect of smoking on lung capacity in women. Summary: 1.The main difference between observational study and experiments is in the way the observation is done. 2.In an experiment, the researcher will undertake some experiment and not just make observations. In observational study, the researcher simply makes an observation and arrives at a conclusion. 3.In observational study, no experiment is conducted. In this type of study the researcher relies more on data collected. 4.In an experiment, the researcher observes things through various studies. 5.There is human intervention in experiments whereas there is no human intervention in observational study. 6.Hawthorne studies are a good example for experiments. 7.The study to determine the relation between smoking and lung cancer is a typical example for observational study.
designed experiment
An experiment allows for the researcher to manipulate variables and establish cause-and-effect relationships more effectively than an observational study. This control helps to minimize confounding variables and biases, making the results more reliable. Additionally, experiments often involve random assignment, which enhances the ability to draw conclusions about the relationships being studied.
cause and effect
An experiment can establish causation by manipulating variables and controlling for potential confounding factors, while an observational study can only show correlation. Experiments allow researchers to directly test hypotheses and determine the effects of specific interventions, providing stronger evidence for causal relationships. Additionally, experiments can help establish a cause-and-effect relationship with higher confidence due to their randomized controlled design.

Observational study
If we're talking about statistics: There is no superior observational study, each study has its advantages and disadvantages.
Sociology is the study of society, social relationships, and institutions, while logic is the study of reasoning and argumentation. Sociology focuses on understanding human behavior in groups, whereas logic focuses on principles of valid reasoning and inference. Both disciplines contribute to understanding human behavior and the world around us, but they approach it from different perspectives.
