I want to examine the relationship between gas mileage of cars and the engine size ( displacement in cubic inches). The explanatory variable is?

The explanatory variable is another term for an independent variable.


The explanatory variable in this problem is the engine size.

In this case, the explanatory variable is the engine size or displacement in cubic inches. The explanatory variable is the one that you believe may have an effect on the response variable, which in this case is the gas mileage of cars. To examine the relationship between these two variables, you will need a dataset that includes measurements of both the engine size and the gas mileage for each car. Once you have the data, you can use statistical analysis techniques, such as regression analysis, to determine the strength and direction of the relationship between the two variables.
