Explanation:
George Miller's research: The research on magical number seven was published in 1956 in Psychological Review by George A. Miller.
The cognitive psychologist named George Miller has given the magical number seven. He believed that an individual can process 7 ± 2 objects consciously at a time. The magical number seven plus or minus two demonstrate the capacity of an individual's short-term memory. An individual can store five to nine items in his or her short-term memory at a time.

Multiple Linear Regression: What Is It?
A number of explanatory variables are combined in a statistical process called multiple linear regression (MLR), also referred to as multiple regression. Modeling the linear relationship between the explanatory (independent) factors and response (dependent) variables is the aim of multiple linear regression. Because multiple regression takes into account several explanatory variables, it can be thought of as an extension of ordinary least-squares (OLS) regression.
A single dependent variable and several independent variables can be analyzed using the statistical technique known as multiple regression.

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.
