Question

If I wish to study cause and effect between two variables, I must do which of the following?

A. A correlation
B. An experiment
C. A case study
D. A survey

Answer 1

To study cause and effect between two variables, you must conduct an experiment where all possible variables are controlled.

Step-by-step explanation:

If you wish to study cause and effect between two variables, you must conduct an experiment. In experiments, all possible variables are controlled, allowing for the conclusion that changes in one variable cause changes in another. This is different from observational studies, which can only establish correlation but not causation.
