The explanatory variable tells us that more education among people over 25 years, brings about a reduction in motor deaths.
The response variable is the rate of motor vehicle deaths.
This variable actually responds to the changes in the explanatory variable. The rate of motor vehicle deaths could increase or decrease based on the level of education.

These variables are not known primarily as explanatory variables here in this relationship but they have the ability to affect the result of the study.
3. We have to carry out an experiment first in order to carry out a causal relationship.
