A scatterplot is a graph that plots the relationship between two variables, in this case GPA and IQ scores. It is the best choice because it shows the relationship between the two variables and allows for visual analysis of any potential patterns or trends in the data. A histogram displays the distribution of a single variable, a boxplot is used for displaying the distribution of a variable across multiple categories, and a bivariate plot is not a commonly used term in data visualization.
