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).
Answer:
A strong body of research indeed indicates that the type of neighborhoods in which children grow up can influence many aspects of their development. And that the very division of neighborhoods into rich and poor can cause many of subsequent problems, like crime, drug abuse, school dropouts, discrimination.
As a mayor, you may suggest that for each neighborhood to have its own the school, only further exacerbates these problems, You may propose a project of merging schools of two neighborhoods, but the community is strongly against it. Meanwhile, a locally done research can change the public views and serve as a better justification for your proposal.
The challenges that this research presents are manageable. In particular, the anonymity of the families<u> </u>in the longitudinal study your planning to organize has to be maintained on the side of interpreting and reporting studies results. Respective confidentiality agreements also have to be concluded with all of the participants.
Regarding political issues, increasing social mobility in rich neighborhoods should support be of a supportive factor for this research. Newly rich families often move to rich neighborhoods, while families who have lost their wealth have to move out. In addition, some modern families do not care as much about attributes of their status, especially in the millennial generation, thus it becomes harder to identify how rich or poor a family actually is.
In middle adulthood, a person is most likely to lose an inch in height.
This happens because as we grow older, our bone density lessens (in the spinal column) which results to a collapsed vertebra. Another reason that people lose around an inch in height during middle adulthood is because joint cartilage in adults get exhausted.
