Which type of research method is used to show cause and effect that one variable causes change in another variable?
The experimental research method is typically used to show cause and effect between variables, where one variable is manipulated to observe the effect on another variable. This method involves randomly assigning participants to different conditions and controlling for extraneous variables to establish a causal relationship.
Where are variables displayed when using the POST method?

Is possible to declare a variable in a method and declare it a main?
The same identifier (variable name) may be used for at most one variable in each scope. Each method has its own scope, in addition to the global scope which is accessible from all others. However, each scope would have a different variable than every other scope despite using the same name for it.

Correlational research method assesses the relationship between two variables without implying causation. It examines how changes in one variable are associated with changes in another variable.
What does manipulated variable mean in a scientific method?
In the scientific method, a manipulated variable, also known as the independent variable, is the factor that is deliberately changed or controlled by the researcher to observe its effect on another variable. This allows scientists to establish cause-and-effect relationships in experiments. By varying the manipulated variable, researchers can gather data on how it influences the dependent variable, which is the outcome being measured.
What is the scope of any variable?
The Scope of a variable defines the areas of a program where this variable would be visible and can be used. For ex: a. Method variables - are visible only inside the method where they are declared and hence their scope is only the method b. Class variables - are visible inside the class and can be used by any method inside the class and hence their scope is the whole class.
A variable that is declared inside a method is called variable?
It is called a local variable since it only exists inside the method.
