The purpose of a scatter plot is to visually represent the relationship or correlation between two variables. It is often used in data analysis to identify patterns or trends in the data. A scatter plot consists of a series of points plotted on a graph, where each point represents a combination of values for the two variables being studied. By examining the distribution of the points on the graph, you can determine the strength and direction of the relationship between the two variables. In this case, the correct answer would be D, as a scatter plot helps in analyzing the relationship between different variables.
