Answer:

Explanation:

La investigación experimental es cualquier investigación realizada con un enfoque científico, donde un conjunto de variables se mantienen constantes, mientras que el otro conjunto de variables se miden como sujeto del experimento.

La investigación experimental es uno de los métodos de investigación cuantitativa principales.

El ejemplo más simple de una investigación experimental es una prueba de laboratorio. Siempre que la investigación se realice bajo condiciones científicamente aceptables, se califica como una investigación experimental.

Una verdadera investigación experimental se considera exitosa sólo cuando el investigador confirma que un cambio en la variable dependiente se debe a la manipulación de la variable independiente.

Es importante para una investigación experimental establecer la causa y el efecto de un fenómeno, lo que significa que debe ser claro que los efectos observados en un experimento se deben a la causa.

Como es natural, puede ser que los eventos que ocurran sean confusos y no permitan a los investigadores establecer conclusiones fácilmente.

Por ejemplo, un estudiante de cardiología realiza una investigación para comprender el efecto de los alimentos en el colesterol y resulta que la mayoría de los pacientes con problemas de corazón no son vegetarianos ni tienen diabetes, es porque comen carne (supongamos). Este último puede ser un aspecto (causa) que puede provocar un ataque cardiaco (efecto).

Fed [463]

Answer:

The President.

Explanation:

The United States Armed Forces, made up of the Army, Navy, Air Force, Coast Guard, Space Force and Marines, are the body in charge of providing national defense against external aggressions from other nations or from foreign insurgent or terrorist groups.

The President of the United States, according to Article II of the Constitution, exercises the role of commander-in-chief of the armed forces, which is why he is the one who has the final authority in all matters related to the military operations of the United States. Even so, this situation is subject to a system of checks and balances, such as the authorization that Congress must give when declaring war on another nation.

IRISSAK [1]
In journalism, yellow journalism is a pejorative reference given to various practices or tendencies of news media organizations which, by the standards of journalistic professionalism, are considered to be unprofessional and detrimental to the principles of journalistic integrity as a whole. The term typically refers to sensationalism in news reporting that bears only a superficial resemblance to the profession of journalism. The term "infotainment" was coined to refer to news programming that blends journalism and entertainment in a way which, critics argue, diminishes the news value and professionalism of the reporting.

The phrase "media bias" is a related term which is used in political rhetoric to assert a broad political bias within news media organizations. Its common usage derives from news media talk shows where an organization's functionaries and personalities tend to direct discussion away from issues in professional journalism to issues in politics.

Hope that helps!
