A scatter diagram is the most useful type of graph in determining if two variables are correlated. It displays the relationship between two variables by plotting their values on a graph, with each point representing an observation of the two variables. The pattern of the points can reveal whether the variables are positively, negatively, or not correlated, which is valuable information for understanding the relationship between them.
