Expert writing Tips
Best practice
When discussing the connection between two distinct concepts, use "the relationship between" to clearly establish the focus on their interaction. For example, "The relationship between supply and demand influences market prices."
Common error
Avoid assuming that a relationship between two variables implies causation. Just because two things are related does not mean one causes the other. For instance, the relationship between ice cream sales and crime rates does not mean that ice cream causes crime.
