LSSGB: Which of the following quality tools is used to rank all categories, making apparent the vital few and the trivial many?

OPTIONS

ANSWER

Pareto diagrams

EXPLANATION

Flow charts visually present a process showing the main steps, branches, and outcomes of that process. A scatter diagram visually displays the correlation between two or more variables. Control charts are used to detect changes in a predictable process and indicate when adjustment is necessary. Options a, b, and c are incorrect. A Pareto diagram is used to show all categories by rank, indicating the vital few and the trivial many.
