An analyst wants to include a graph in a quarterly sales report that shows the comparison between two quantitative variables. Which of the following visual diagrams can the analyst use to most effectively represent this relationship?
A scatter plot is specifically designed to display and compare the relationship between two quantitative variables. Each point represents an observation with values on both axes, revealing patterns, correlations, or trends between the two variables. Scatter plots are a fundamental tool in data analysis for visualizing variable-to-variable relationships.
