ASQ CQE Exam - Topic 3 Question 120 Discussion

Actual exam question for ASQ's CQE exam

Question #: 120
Topic #: 3

[All CQE Questions]

An increase in the overall length of a recently qualified metal component has been observed and the quality engineer suspects that the storage temperature could be a factor that has affected the overall length. Which of the following tools could be used to assess this relationship?

AAffinity diagram

BScatter diagram

CHistogram

DCause and effect diagram

Show Suggested Answer

Suggested Answer: B

A scatter diagram is used to assess the relationship between two variables. In this case, it can be used to analyze the relationship between storage temperature and the overall length of the metal component. A scatter diagram helps in visualizing any correlation between the two variables. Reference: 'The Quality Toolbox' by Nancy R. Tague, which provides descriptions and uses for various quality tools including scatter diagrams.

C) Histogram could work too. Might be able to spot any patterns or outliers in the component lengths that way. Just a thought!

I'd go with D) Cause and effect diagram. Gotta get to the root of this length issue, you know? Scatter diagram is good, but the cause and effect diagram will really help us dig deeper.

B) Scatter diagram seems like the obvious choice here. It's perfect for visualizing the relationship between storage temperature and component length.

I recall using affinity diagrams for organizing ideas, but I don't see how that fits this situation. Scatter diagram seems more relevant.

I feel like a histogram could help visualize the distribution of lengths, but it doesn't directly show the relationship with temperature, right?

I'm not entirely sure, but I remember practicing with cause and effect diagrams for identifying factors. Could that apply here?

I think a scatter diagram might be the right choice here since it can show the relationship between temperature and length.

A histogram could also be useful here, right? We could use it to look at the distribution of component lengths and see if there are any outliers or unusual patterns that might be related to the storage temperature.

I'm leaning towards the scatter diagram as well. It's a great way to get a visual on the data and see if there's any clear pattern or trend. Plus, it's a pretty straightforward tool that I feel comfortable using in the exam setting.

Okay, let's think this through. We want to assess the relationship between storage temperature and component length, so a scatter diagram does seem like the logical choice. That will let us see if there's a linear or non-linear correlation between the two variables.

I'm a bit unsure about this one. Is a scatter diagram really the best tool here? I'm wondering if a cause and effect diagram might help us identify all the potential factors that could be influencing the component length.

Hmm, this seems like a classic case of trying to find the relationship between two variables. I'd probably go with a scatter diagram to visualize the data and see if there's any correlation between storage temperature and component length.
