In an experimental investigation,what is the variable that the researcher changes or manipulates in order to see its effects is
NikAS [45]

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).
