Formas en las que se puede recopilar la data experimental que va a ser analizada e interpretada.​
Cerrena [4.2K]

Answer:

Experimento, observación directa, encuesta, entrevista, etc.

Explanation:

El método de investigación implica el ordenamiento sistemático de la información científica con el objetivo final de confirmar o rechazar una hipótesis de trabajo. Antes de comenzar una investigación, es imperativo conocer cuales son los tipos de datos que permitirán responder las preguntas planteadas en dicho proceso. Para ello, es necesario tener en cuenta que los datos resultan útiles cuando pueden ser clasificados y/o medidos, es decir, cuando ellos representan variables con diferentes estados (cuantitativos) o cuyos valores son fluctuantes entre sí (cuantitativos). Los datos deben cumplir una serie de requisitos, estos deben ser confiables (no falseables), objetivos (presentar el mismo valor en medidas independientes) y válidos (útiles para la investigación). Los métodos más comúnmente utilizados para recopilar datos son los siguientes: 1-observación directa: por ejemplo, mediante la observación de variables en su contexto natural; 2-experimentación, donde la información es obtenida en condiciones controlada; 3-encuestas, las cuales consisten en la toma de datos estadísticamente normalizados; 4-entrevistas, que representan un método indirecto de obtención de datos cualitativos.

Check Your Understanding<br> Question: What is an adaptation?
AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
