Which variable is the one that explains the relationship between independent variable and dependent variable?

Which variable is the one that explains the relationship between independent variable and dependent variable?

A hypothesis states a presumed relationship between two variables in a way that can be tested with empirical data. It may take the form of a cause-effect statement, or an “if x,…then y” statement. The cause is called the independent variable; and the effect is called the dependent variable.

How to check the relationship between independent and dependent variables?

If the correlation indicates no relationship between the investigated variable then you have to drop that feature after justifying the drop with an exhaustive EDA, then try to check the effect of other variables on your dependent variable if EDA suggests positive results then you can fit a reg model.

When do you need to include multiple dependent variables?

Even if you are primarily interested in the relationship between an independent variable and one primary dependent variable, there are usually several more questions that you can answer easily by including multiple dependent variables. Often a researcher wants to know how an independent variable affects several distinct dependent variables.

Are there any studies that include multiple independent variables?

Just as it is common for studies in psychology to include multiple dependent variables, it is also common for them to include multiple independent variables. Schnall and her colleagues studied the effect of both disgust and private body consciousness in the same study.

Why are so many dependent variables used in psychology?

Researchers in psychology often include multiple dependent variables in their studies. The primary reason is that this easily allows them to answer more research questions with minimal additional effort. When an independent variable is a construct that is manipulated indirectly, it is a good idea to include a manipulation check.
