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 beâ a:

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

Answer 1

A scatter diagram would be the most appropriate tool for analyzing the relationship between the number of process failures and the total units produced in a fiberglass molding operation.

Step-by-step explanation:

The best tool to analyze the relationship between the number of process failures and the total number of units produced in a fiberglass molding operation would be a scatter diagram. A scatter diagram is a graph used to visualize the relationship between two quantitative variables, and it can help to identify any patterns, trends, or correlations. This graphical representation plots one variable along the x-axis (total units produced) and the other variable along the y-axis (number of process failures), and it would allow the manager to visually assess whether there is a correlation between the two factors.

Answer 2

D) scatter diagram

Step-by-step explanation:

A scatter diagram presents a graph of the values of two variables which are plotted along two axes, e.g. x and y axes, in order to obtain points or dots that usually show the relationship between the values of the two variables.

A scatter graph is useful in knowing the potential root causes of a particular problem(s), to know if there is any cause and effect relationship, and to ascertain if the cause of two related effects are the same or not, and among others.

Therefore, a tool most useful in the analysis of the manager of a fiberglass molding operation would be a scatter diagram.

I wish you the best.
