cause and effect
If the observer and the observing equipment are unbiased then there is no reason for the study to be biased.
There are a number of ways, but I would just use an observational study.
Descriptive research includes observational methods, case study methods, and survey methods. They are used to describe situations instead of make predictions about them.
Observations and measurements recorded during an experiment are called results. These results can help to make a conclusion or theory or become the object of further study.
Probably not. I would challenge anyone to prove that with a scientific study.
An experiment can help rule out alternative explanations. Thus, it is a stronger research design.
In Vivo
in an experiment, the researcher manipulates a variable
Because it's fun

To make "the most correctable solution"
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.
Observational study
If we're talking about statistics: There is no superior observational study, each study has its advantages and disadvantages.
