Question

Quizplus · Accepted Answer

A better graphical representation for comparing three variables such as total dollars spent on research and development, total sales dollars, and total employee salaries would be a bar chart or a scatter plot matrix, depending on the nature of the data and the relationships being explored. A line chart is typically used to display trends over time, not to compare three distinct variables.
