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 lung capacity versus marathon time for a runner. The response variable is the marathon time and the explanatory variable is the lung capacity. The scatterplot should be expected to have a negative direction and be linear with small variation.
