well first you take out bread then you take out meat, cheese, and mayo then you put them all together and you have yourself a experimental/observational sandwich
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.
Data will be either qualitative (non numerical description) or quantative (numerical values assigned to a property). To give you an example, a meterologist may describe the sky on a particular day as cloudy (qualitative) with a 5 mile per hour wind (quantative). Studies can be classified as experimental studies or observational studies. The experimental study means that the scientist is able to treat or alter in some way the population. Medical studies of drugs frequently conduct experimental studies and collect experimental data. Observational studies, we collect data without altering the population. A good example is astronomical studies, where it is impossible to alter the population. Scientific studies need to be thorough investigations relying on good data and sufficient quantity of data in order to reach conclusions.

Observational studies observe natural phenomena without intervention, while experimental studies manipulate variables to determine cause and effect. Observational studies are useful for understanding associations, while experimental studies can establish causal relationships between variables. Experimental studies involve random assignment of participants to groups, while observational studies rely on natural groupings.

Evolution is documented in both realtime experimental and observational data, as well as in the fossil and genomic record.
