Question

A manager of a fiberglass molding operation suspects that the number of process failures is related to the number of total units produced of a particular product. A tool most useful in this analysis would be​ a:

A) checklist.
B) cause-and-effect diagram.
C) Pareto chart.
D) scatter diagram.

Answer 1

Answer: D) scatter diagram.

Step-by-step explanation:

Scatter diagram is a graph with two variables values plotted along two axis in which the pattern reveals if there is any correlation through the resulting points/ dots. It is used to determine the relationship between two variables in which both are along the same curve.

Scatter diagram is used when:

• Numerical data are in pairs.

•To determine relationship between two variables.

•To determine the effect and cause of two variables when they appear similar.

•To determine the root cause of a potential problem.
