Understand that a scatterplot is a graphical tool used in statistics to visualize data.
Recognize that a scatterplot displays points on a coordinate plane where each point represents an observation with two quantitative variables: one on the x-axis and one on the y-axis.
Recall that the main purpose of a scatterplot is to show the relationship or association between these two quantitative variables, such as whether they have a positive, negative, or no correlation.
Compare this purpose with other types of graphs: histograms show frequency distributions of a single quantitative variable, bar charts summarize categorical data, and boxplots or t-tests compare means between groups.
Conclude that the best description of a scatterplot's purpose is to display the relationship between two quantitative variables.
