A study was conducted comparing two quantitative variables. Which type of graphical display is appropriate for displaying this relationship?

A two-way table is typically used to summarize categorical data by displaying the frequency distribution of variables across rows and columns. While it can show relationships between two variables, it is not suited for quantitative data, as it does not provide visual insights into the relationship like a scatterplot does.

A decision table is a tool used for modeling decision-making processes, organizing potential actions based on different conditions. It is not intended for data visualization and does not display relationships between quantitative variables. Thus, it is not appropriate for this scenario.

A side-by-side box plot is useful for comparing distributions of a quantitative variable across different categories. However, it does not effectively illustrate the relationship between two quantitative variables, as it summarizes data through quartiles and does not show individual data point relationships like a scatterplot.
