A scatter diagram is a graph that uses dots to represent data points from two variables. The position of each dot on the horizontal and vertical axis corresponds to the values of the two variables for that data point. Scatter diagrams are used to show the relationship between two quantitative variables, such as the correlation between the number of hours of study and the exam score. Therefore, it is the best choice for representing the relationship between two quantitative variables.

Pie charts are used to show the proportion of categorical data, while histograms are used to show the distribution of a single variable. Crosstabulations are used to show the relationship between two categorical variables. Therefore, these options are not appropriate for representing the relationship between two quantitative variables.
