Quizplus · Accepted Answer

Correlation is a research method used to measure the relationship between two variables without controlling any variables. In this method, the researcher observes and measures the degree to which changes in one variable are associated with changes in another variable. The researcher does not manipulate any variables or control any conditions, and only observes the natural relationship between the variables.
