Question

Suppose a researcher collects data for the following pair of variables. The researcher wants to make a scatterplot. Identify the response and explanatory variables. What would the researcher expect to see in the scatterplot? Discuss the direction, curvature, and variation.

Measuring the amount of heating oil used versus heating bill for a house.

The response variable is the (amount of heating oil used/heating bill) and the explanatory variable is the (amount of heating oil used/heating bill).

The scatterplot should be expected to have a (negative/positive) direction and be (linear/curved) with (a lot of/small) variation.

Explanation / Answer

The response variable is heating bill and the explanatory variable is the amount of heating oil used.
