Question

Quizplus · Accepted Answer

Class year and GPA are two continuous variables, which can be plotted on a scatter diagram to show the relationship between them. The scatter diagram will show whether there is a positive, negative, or no relationship between the two variables. The other options are not appropriate for this type of data. Contour maps are used to display geographical data, while time-series diagrams are used to display data over time. There is no reason for the data in question to be plotted over a period of time.
