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:
Carl's Perkings Act
Explanation:
The answer is Perkings Act.
This act is named after Carl D. Perkins. This acts helps students and people to study technical courses and increase their knowledge. By allowing the deprived people to study and practice technical things, they will help to strengthen the United States economy.
The full name of this act is Carl D. Perkins Vocational and Technical Education Act. The Federal government of the States authorized this act in the year 1984.
This act ensures access to vocational assessment, counseling, and placement of the disenfranchised groups.
Thus the answer is ---
Carl's Perkings Act
Answer:
D texture of the jumping surface
Explanation:
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
A control experiment can be defined as an experiment in which a condition assumed to be a probable cause of the effect is being compared to the same situation by the scientist without involving or using the suspected condition.
In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.
Furthermore, a controlled variable refers to anything or quantity such as group, person, event, etc., that is held constant by the researcher during an experiment and as such is limited.
In this scenario, you are designing an experiment to find out which type of frog can jump farther. Thus, the controlled variable (variable that does not change) in this experiment is the texture of the jumping surface because it is where all the frogs would be tested on i.e used for the jumping test.
The Jacques Cartier’s names of ships are Grande Hermine, Petite Hermine, Émérillon and Saint-Brieux. The Grande Hermine was given to Cartier by the king Francois I of France in 1534. It was used in his voyage to North America in 1535- 1536 and in 1541- 1546, during his third voyage to San Lorenzo River. Petite Hermine also was used by Cartier’s in his first voyage, but it was abandoned by sailors when they died because of the critical climate condition. Émérillon and Saint-Brieux were used in the voyage of 1541- 1542, accompanied Cartier`s and his mariners to his adventures until he ends his discoveries and he died in 1557.
