Explanation

A scatter diagram (also called a scatter plot or correlation chart) is used to display the relationship between two variables and helps determine whether a correlation exists between them. It is one of the seven basic quality tools in the PMBOK Guide. A cause-and-effect diagram (Option B) identifies root causes of a problem, not correlations between two variables. A histogram (Option C) shows frequency distribution of a single variable. Control charts (Option D) monitor process stability over time. Only the scatter diagram is designed specifically to test for correlation between two elements.
