When two variables are statistically related, a cause-and-effect relationship exists.

Question

Quizplus · Accepted Answer

Statistical dependence or correlation between two variables does not necessarily imply a cause-and-effect relationship. There may be other factors or variables that influence this relationship, leading to a spurious correlation or a coincidental association. To establish causality, we need to conduct experimental research that manipulates the independent variable and measures its effects on the dependent variable while controlling for extraneous variables.
