Answer: Experimental Method
Explanation:
The field of psychology has several research methods for the study of human behavior and its different forms. There is what is called experimental psychology, which expresses that psychological phenomena can be studied through the experimental method through observation, manipulation, and recording of the variables that affect the object of study.
The experimental method expresses that one or several variables are manipulated to determine their effect on an independent variable. In this case, rap music is set to see how it influences aggressive behavior and is analyzed because this type of music may have a certain relationship with the behavior.
In the experimental method, humans and animals are used to know the behavior that an individual may have when exposed to other variables that may interfere with their behavior. This type of experiment is usually done more in animals than in people because researchers can dispose of them at any time and in turn have more control. Besides, some experiments cannot be carried out in human beings due to ethical issues since if they are carried out they could put the person's health at stake.

Answer:
3. This will lead to a biased sample because the type of students who take Psychology and Law may be different from the type of students who take Introduction to Neuroscience
Explanation:
Professor Kramer wants to measure the level of happiness of his students, and he wants to do so for both his classes. However, he will biased the survey simply because he is considering surveying only the students from one of his classes, who may be very different from the students from the other class.
If Professor Kramer wants to make a unbiased survey, he should either find a way to also apply the survey to the students from the other class, or change the goal of the research to measuring the happiness level of the Psychology and Law class students only.
