Qué papel juega la ética y la moral dentro de un estudio estadístico?

All research projects involve ethical aspects (related to what is right and what is not correct) during the investigation. For example, if it is carried out with human beings, it must take into account that the participants (subjects of study) are adequately informed of what will be done with them, what is the subject of the research, in what they can benefit and how it can damage them, etc. Even if it is with animals, strict guidelines must be followed to avoid causing unnecessary harm. The moral, is a rather temporary aspect (the moral changes according to the time, what 200 years ago could be immoral, for example: manipulate a corps) today, is acceptable as long as again, guidelines are not transgressed anymore established to avoid investigations that neither contribute anything but also cause harm.

The precedent of these guidelines was set during the Second World War and the first half of the 20th century, where atrocious experiments were carried out in humans without benefit or against certain groups (experiments on Jews, twins carried out by Mengele) or vulnerable populations (the experiment on syphilis called "Tuskegee experiment" (1932-1972) conducted in imprisoned African-Americans, many of them illiterate.

They are correctly called "research studies," "clinical trials," "quasi-experimental studies," not "statistical studies," as you mention, Greetings!
