What is “control”? briefly explain in your own words the purpose of control in discovering cause-and-effect relationships, both in everyday learning and social research.

Control is the power to influence or direct peoples behavior or the course of an event
having control in everyday learning and social research is very important because if you have no control then things will most likely go the complete opposite direction of where you want them to go whether it be in everyday learning or social research(is this what you are looking for)

hope this helps
